SP2T Pin Diode Switches
Absorptive and Reflective
Pulsar Microwave's 2-way switches are available in absorptive and reflective designs from 20 MHz to 18 GHz. They are also referred to as single pole, double throw and abbreviated SPDT or SP2T. These switches have a typical VSWR performance of 1.6:1 or better and input power handling of 200 milliwatts maximum. Switching time is 100 nanoseconds, and isolation of 60 dB or greater for most models. Supply voltages are +5V and -5V, with TTL logic control voltage of 0 to 5 volts. Both absorptive and reflective SPDT switches are packaged into Pulsar Microwave's SW2 outline. Configuration is standard with SMA female connectors. Voltage is applied with wire wrap feed thru terminals. The housing serves as electrical ground, and two turret terminals are installed for wiring.
