Description

The HWS421 is a GaAs MMIC SPDT high power

switch in a low cost SOT-26 plastic lead (Pb) free

package. The HWS421 features low insertion loss

with very low DC power consumption. This high

power switch can be used in GSM and PCS

systems as selection of transmit or receive function

for a common antenna.
