Description

The HWS341 is a GaAs MMIC SPDT high

power switch in a low cost SOT-26 plastic

package. The HWS341 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.
