HMC435MS8GE

HMC435MS8G / 435MS8GE v05.0110 Typical Applications Features The HMC435MS8G(E) is ideal for: • Basestations & Repeaters High Isolation: 60 dB @ 1 GHz 50 dB @ 2 GHz • Cellular/3G and WiMAX/4G Positive Control: 0/+5V • Infrastructure and Access Points Input IP3: 51 dBm • CATV/CMTS Non-Reflective Design • Test Instrumentation Ultra Small MSOP-86 Package: 14.8 mm2 Functional Diagram General Description The HMC435MS8G(E) is a non-reflective DC to 4 GHz GaAs MESFET SPDT switch in a low cost 8 lead MSOP8G surface mount package with exposed ground paddle. The switch is ideal for cellular/3G and WiMAX/4G applications yielding up to 60 dB isolation, low 0.8 dB insertion loss and +50 dBm input IP3. Power handling is excellent up through the 3.8 GHz WiMAX band with the switch offering a P1dB compression of +31 dBm. On-chip circuitry allows positive voltage control of 0/+5 Volts at very low DC currents.
