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
