High Power Switch Design Application
A T-R switch incorporating SMP1302 PIN diodes covering
2.0155 GHz to 2.0195 GHz has been designed and
tested. The switch operated safely at transmitter power
of 41dBm CW (12.6 W) with low insertion loss (0.42 dB)
and high receiver isolation (37 dB). 1 dB compression
occurred at higher than 50 dBm. In the receive state the
switch performed with 0.45 dB insertion loss and 37.8 dB
transmitter isolation.
The circuit is based on a quarter wave design utilizing two
shunt connected SMP1302 diodes. In the transmit state
the Bias 1 is set at 0 mA and Bias 2 is set at 50 mA; in the
receive state Bias 1 is set at 50 mA and Bias 2 is set at 0 mA.
