High frequency power divider Rogers PCB aplication

High frequency power divider Rogers PCB aplication
The previous ROG blog offered guidance on selecting PCB materials for high-frequency circuits with coupled features and much of that advice can be applied to any search for circuit materials for power dividers/combiners and couplers. As with many circuit designs, the dielectric constant (Dk) is often a starting point when surveying different PCB materials, and designers of power dividers/combiners and couplers generally tend towards using circuit materials with higher Dk values, since those materials support efficient coupling of electromagnetic (EM) energy using smaller circuit features than materials with lower Dk values. A problem with higher-Dk circuit materials, as the earlier blog explained, is the tendency towards anisotropic Dk characteristics across a circuit board, or having different Dk values in the x, y, and z axes of the circuit board material. Wide variations in Dk, also within one axis of the material, can make it difficult to achieve transmission lines with consistent impedance.

Maintaining consistent impedance is critical to achieving high performance in power dividers/combiners and couplers, where variations in Dk (and impedance) can result in uneven distributions of EM energy and uneven power distributions. Fortunately, as noted in the previous blog for circuits with coupled features, commercial PCB materials with excellent isotropic behavior are available for these types of applications, such as the TMM® 10i circuit materials from Rogers Corp. These materials exhibit a relatively high Dk value of 9.8 and the value is consistent within +/-0.245 of 9.8 for all three axes of the circuit material (as measured at 10 GHz). This translates into consistent impedance for the transmission lines of power dividers/combiners and couplers, resulting in consistent and predictably distribution of EM energy in these component. For a PCB material with even higher Dk value, TMM 13i laminate has a Dk value of 12.85 which remains within +/-0.35 of that value (at 10 GHz) for all three axes. In fact, for those interested in reviewing the chief material parameters to consider when impedance matching is of prime importance (for low VSWR performance), an earlier blog highlighted those key materials, using the RO3010™ and RO3035™ circuit materials from Rogers Corp. as examples.

Interest in UWB systems and components has increased steadily since about 2002, when UWB communications systems concepts were first introduced and developed. A number of components for UWB applications have been designed and fabricated since that time.1-6 Power dividers are among the most crucial of RF/microwave devices, since signals must be split and channeled through communications signals for proper detection and processing.

To meet the requirements for UWB systems, a number of UWB power dividers have been developed, with different configurations based on traditional Wilkinson power dividers.7-9 For the sake of shrinking the dimensions of power dividers for UWB applications, slotline techniques have been studied and applied. As an example, a single-wavelength slotline was applied to structure a noncoplanar, in-phase UWB compact power divider with a flat passband over the UWB frequency range.10 By adding one circular stub at the end of each output branch as compensatory circuits, it was possible to extend the operating frequency range of the power divider, and also helped to achieve a flat passband.11,12

The high thermal

Of course, consistent Dk and impedance is only one PCB material parameter to consider when designing power dividers/combiners and couplers. Minimizing insertion loss is usually an important goal when designing any power divider/combiner or coupler circuit. Ideally, a two-way Wilkinson power divider would provide two output ports each 3-dB or one-half the power level of the EM energy applied to the input port. In reality, every power divider/combiner circuit (and coupler) will suffer some amount of insertion loss, usually depending upon frequency (with loss increasing as frequency increases), and a consideration for a PCB material for a power divider/combiner is how to manage or, hopefully, minimize, the insertion loss of the circuit.

Power divider, is a way to the input signal energy is divided into two or more output equal or unequal energy devices, but also in turn multi-channel signal energy output all the way, this May also be referred to as a combiner. A power divider between the output ports should ensure a certain degree of isolation. Power divider according to the output is usually divided into one into two (one input two outputs), one three (one input three output) and so on. The main technical parameters of the power splitter are power loss (including insertion loss, distribution loss and reflection loss), the voltage standing wave ratio of each port, the isolation between the power distribution ports, amplitude balance, phase balance, power capacity and frequency band Width and so on.

The most common form of directional coupler is a pair of coupled transmission lines. They can be realised in a number of technologies including coaxial and the planar technologies (stripline and microstrip). An implementation in stripline is shown in figure 4 of a quarter-wavelength (λ/4) directional coupler. The power on the coupled line flows in the opposite direction to the power on the main line, hence the port arrangement is not the same as shown in figure 1, but the numbering remains the same. For this reason it is sometimes called a backward coupler.[13]

The main line is the section between ports 1 and 2 and the coupled line is the section between ports 3 and 4. Since the directional coupler is a linear device, the notations on figure 1 are arbitrary. Any port can be the input, (an example is seen in figure 20) which will result in the directly connected port being the transmitted port, the adjacent port being the coupled port, and the diagonal port being the isolated port. On some directional couplers, the main line is designed for high power operation (large connectors), while the coupled port may use a small connector, such as an SMA connector. The internal load power rating may also limit operation on the coupled line.[14]

Figure 5. Short section directional coupler

Figure 6. Short section directional coupler with 50 Ω main line and 100 Ω coupled line

Figure 7. Lumped element equivalent circuit of the couplers depicted in figures 5 and 6
Accuracy of coupling factor depends on the dimensional tolerances for the spacing of the two coupled lines. For planar printed technologies this comes down to the resolution of the printing process which determines the minimum track width that can be produced and also puts a limit on how close the lines can be placed to each other. This becomes a problem when very tight coupling is required and 3 dB couplers often use a different design. However, tightly coupled lines can be produced in air stripline which also permits manufacture by printed planar technology. In this design the two lines are printed on opposite sides of the dielectric rather than side by side. The coupling of the two lines across their width is much greater than the coupling when they are edge-on to each other.[15]

The insertion loss in a passive high-frequency component, such as a power divider/combiner or coupler, is actually the sum of a number of separate losses, including dielectric loss, conductor loss, radiation loss, and leakage loss. While some of these losses can be controlled through careful circuit design, they may also be dependent upon the capabilities of the PCB material and can be minimized through thoughtful selection of PCB material. Leakage loss is minimized in PCB materials from Rogers Corp., for example, since the materials are designed with high volume resistivity to provide high isolation with low leakage loss for fabricated transmission lines. Loss can also result from impedance mismatches (VSWR losses), which can be minimized by the choice of PCB materials with consistent Dk characteristics.

Minimizing loss is of particular importance in power combiners/dividers and couplers that are intended to handle higher power levels, since losses at higher power levels turn to heat that must be dissipated by the component and its PCB material, and that heat can have an effect on the Dk value (and impedance) of the material.

In short, when designing and fabricating high-frequency power dividers/combiners and couplers, the choice of PCB material should be based on a number of different key material properties, including Dk value, consistency of Dk across the material and with environmental factors such as temperature, minimal material losses, including dielectric and conductor losses, and power-handling capability. Starting with PCB material that is matched to the application can help ensure the success of a high-frequency power divider/combiner or coupler design.
