The HMC221B is a single-pole, double-throw (SPDT) switchspecified from 10 kHz to 3 GHz in a 6-lead SOT-23 plastic package.This switch offers a very low insertion loss of less than 0.8 dBup to 3 GHz and is well suited for receiver and filter switchingapplications that require low insertion loss and a small size.
The RF1 and RF2 pins are reflective shorts when in an off state,and the two control voltages (the A and B pins) require a minimaldc bias current. Note that the HMC197B exhibits a similarperformance in an alternate pinout.
