SP3T RF Pin Diode Switches to 18 GHz
Pulsar Microwave manufactures 3-way absorptive and reflective switches for use in 50-ohm systems. These SP3T switches operate from 100 MHz to 18 GHz and handle 200 mW input power. VSWR performance is often 1.6:1 or better with 100 ns switching time. Minimum isolation of 60 dB is specified for most units. Absorptive and reflective switches require +5V and -5V power supply to function. Control logic is from 0 to +5 volts. All voltage and ground connections are made by feed thru and turret terminals, respectively.
