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.

FEATURES
   Low insertion loss: 0.4 dB typical
   Input third-order intercept (IP3): 55 dBm typical
   Positive control: 0 V/3 V
   Ultrasmall package: SOT-23

APPLICATIONS
   Industrial, scientific and medical (ISM)
   PCMCIA wireless cards
   Cellular applications
