General Description
The HMC199MS8 is a low-cost dual SPDT GaAs
“bypass” switch in an 8-lead MSOP package cover-
ing DC to 2.5 GHz. This four RF port component
integrates two SPDT switches and a through line
onto a single IC. The design provides low insertion
loss of less than 0.5 dB while switching passive or
active external circuit 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 con-
trol inputs compatible with CMOS and most TTL
logic families. Applications include LNA or filter
bypass switching and single bit attenuator switch-
ing.
