General Description
The HMC199MS8 is a low-cost dual SPDT
GaAs “bypass” switch in an 8-lead MSOP
package covering DC to 2.5 GHz. This
four RF port component integrates two
SPDT switches and a through line onto a
2
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 35 to 20 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 for cellular,
PCS, and ISM base stations.
