Typical Applications
The HMC199MS8 / 199MS8E is ideal for:
Cellular
ISM Basestations
PCS
The HMC199MS8 & HMC199MS8E are low-cost
general purpose dual SPDT GaAs “bypass” switches
in 8-lead MSOP packages covering DC to 2.5 GHz.
These four-RF- port components integrate two SPDT
switches and a through line onto a single IC. The
designs provide low insertion loss of less than 0.5
dB while switching passive or active external cir-
cuit components in and out of the signal path. Port
to port isolations are typically 25 to 30 dB. On-chip
circuitry enables positive voltage control operation at
very low DC currents with control inputs compatible
with CMOS and most TTL logic families. Applications
include LNA or filter bypass switching and single bit
attenuator switching. The HMC199MS8E is a RoHS-
compliant product.
