Description

Millitech series PSP single-pole, single-throw (SPST) PIN switches cover the frequency range from 18 to 100 GHz. Full waveguide bandwidth performance can be achieved, upon request, up to 75 GHz (WR-15) with broadband operation beyond 75 GHz. Two switching speeds are available for these PIN switches. The standard switching speed is typically 20 ns from low insertion loss state to isolation state, 150 ns from isolation state to low insertion loss state. Millitech also offers high speed switches (series PSH) with switching times as low as 2 ns.

Series PSP switches can be ordered either with or without a driver. The switching speed of the PIN switch is driver dependent. In addition to being used for pulse modulation and receiver protection applications, these units can also be used as voltage-controlled variable attenuators (see series VCA). Series PDT single-pole, double-throw (SPDT) switches and series PSN multi-throw are also offered.

*1 - Switching speed specifications apply to any switch/driver combination. Driver propagation delay (10 ns max) not included. Switching speed is driver dependant. See Figure 1 below for explanation of switching speeds.
*2 - Measured in PASS state only.
*3 - Forward current (positive supply) corresponds to isolation state, reverse current (negative supply) to low insertion loss state. Driver control input is TTL compatible with SMA connector.
*4 - DC bias input negative supply voltage can be operated from -5 Vdc to -12 Vdc.

A =Flange Type
  • R - round(WR-22 through WR-10 only)
  • S - square (WR-42 and WR-28 only)
B = Driver
  • I - internal driver (standard)
  • W - without driver
