RF/Microwave switches are widely used in microwave measurement systems,
telecommunication and radar applications. The main purposes of RF switches are
Tx-Rx switching, band select and switching the signal between different paths. Thus,
they are key circuits especially in T/R modules. Wideband operation is an important
criterion in EW applications. High power handling is also a key feature especially
for radars detecting long range.
In this study, different types of high power solid state switches operating at X-Band
are designed, fabricated and measured. The main objectives are small size and high
power handling while keeping good return loss and low insertion loss. The related
studies are investigated and analyzed. Solutions for increasing the power handling
are investigated, related calculations are done. Better bias conditions are also
analyzed. The measurement results are compared with simulations and analysis.
Circuit designs and simulations are performed using AWR® / and CST® / .
