| HMC194MS8 / 194MS8E v05.0105 GaAs MMIC SPDT SWITCH DC - 3 GHz Typical Applications The HMC194MS8 /HMC194MS8E is ideal for: * Cellular/PCS Base Stations * Portable Wireless * MMDS & WirelessLAN Features Ultra Small Package: MSOP8 High Isolation: 50 dB Positive Control: 0/+3V to 0/+7V 8 SWITCHES - SMT Functional Diagram General Description The HMC194MS8 & HMC194MS8E 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 high isolation with minimal insertion loss in medium and low power applications. On chip circuitry allows positive voltage control operation at very low DC currents with control inputs compatible with CMOS and most TTL logic families. RF1 and RF2 are reflective opens when "OFF".
