General Description
The HMC199MS8(E) is a low-cost general purpose dual SPDT GaAs “bypass” switch in an 8-lead MSOP package 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 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 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.
