- Abstract
A novel quasi symmetrical three‐way Gysel power divider with frequency‐independent isolation and impedance matching is proposed. Equal magnitudes of the reflection coefficients for the input and the output ports of the three‐way divider can be obtained despite the asymmetrical structure and the different terminal impedances. The divider is analyzed in terms of its equivalent four‐port network. Quasi symmetrical property (|S11| = |Sii|, i = 2‐4) is proved which means the input port (port. 1) will automatch when the output ports are matched. Closed‐form equations are derived for the design. For verification, based on the microstrip/slotline PI, two examples, which include a three‐way Gysel PD with port impedances (50, 50, 50, 50) Ω, and an ultra‐wideband three way Gysel PD with port impedances (50, 100, 100, 100) Ω with the center frequency of 4 GHZ are designed, fabricated, and measured respectively. The measured results are in great agreement with the simulated ones.
