SP4T Pin Diode Switches
Absorptive and Reflective
The 4-way series of absorptive and reflective switches operate from 100 MHz to 16 GHz. They are rated at 200 mW maximum input power and have a switching time of 100 ns. SP4T switches that operate up to 8 GHz have a maximum VSWR of 1.6:1 and minimum isolation of 60 dB. All absorptive and reflective switches manufactured by Pulsar Microwave require both positive and negative 5-volt supplies. Additionally, the TTL control logic operates from 0 to +5 VDC. Voltage connection is made with feed thru terminals. Ground connection is made through the chassis and turret terminals.
