Functional Diagram

General Description

The HMC349MS8G is a high isolation non-

reﬂective DC to 4 GHz GaAs MESFET SPDT

switch in a low cost 8 lead MSOP8G surface

mount package with an exposed ground paddle.

The switch is ideal for cellular/PCS/3G basestation

applications yielding 50 to 60 dB isolation, low 0.8

dB insertion loss and +52 dBm input IP3. Power

handling is excellent up through the 3.5 GHz WLL

band with the switch offering a P1dB compression

point of +31 dBm. On-chip circuitry allows a

single positive voltage control of 0/+5 Volts at very

low DC currents. An enable input (EN) set to logic

high will put the switch in an “all off” state.

Electrical Speciﬁcations,T_A= +25° C, Vctl = 0/+5 Vdc, Vdd = +5 Vdc, 50 Ohm System
