HMC435MS8G / 435MS8GE v03.0607 SPDT NON-REFLECTIVE SWITCH, DC - 4.0 GHz Typical Applications The HMC435MS8G / HMC435MS8GE is ideal for: • Basestation Infrastructure • MMDS & 3.5 GHz WLL • CATV/CMTS • Test Instrumentation Features High Isolation: 60 dB @ 1 GHz 50 dB @ 2 GHz Positive Control: 0/+5V 51 dBm Input IP3 Non-Reflective Design MS8G SMT Package, 14.8 mm2 9 SWITCHES - SMT Functional Diagram General Description The HMC435MS8G & HMC435MS8GE are nonreflective DC to 4 GHz GaAs MESFET SPDT switches in low cost 8 lead MSOP8G surface mount packages with exposed ground paddles. The switch is ideal for cellular/PCS/3G basestation applications yielding 50 to 60 dB isolation, low 0.8 dB insertion loss and +50 dBm input IP3. Power handling is excellent up through the 3.5 GHz WLL band with the switch offering a P1dB compression point of +31 dBm. Onchip circuitry allows positive voltage control of 0/+5 Volts at very low DC currents.
