HMC194AMS8 / 194AMS8E v00.0812 GaAs MMIC SPDT SWITCH DC - 3 GHz Typical Applications Features t he h Mc 194AMS8 /h Mc 194AMS8e is ideal for: Ultra Small Package: MSOP8 Cellular/PCS Base Stations h igh isolation: 50 dB Portable Wireless Positive c ontrol: 0/+3V to 0/+7V MMDS & WirelessLAN Functional Diagram General Description The HMC194AMS8 & HMC194AMS8E are low-cost SPDT switches in 8-lead MSOP packages for use in applications which require high isolation between two RF paths. The devices can control signals from DC to 3 GHz and have been optimized to provide extremely w high isolation with minimal insertion loss in medium and low power applications. On chip circuitry allows positive voltage control operation at very low DC cur- rents with control inputs compatible with CMOS and most TTL logic families. RF1 and RF2 are reflective opens when OFF.
