GENERAL DESCRIPTION
The HMC221B is a single-pole, double-throw (SPDT) switch
specified 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 dB
up to 3 GHz and is well suited for receiver and filter switching
applications 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 minimal
dc bias current. Note that the HMC197B exhibits a similar
performance in an alternate pinout.
