| v01.0503 MICROWAVE CORPORATION HMC435MS8G SPDT NON-REFLECTIVE SWITCH, DC - 4.0 GHz 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 Typical Applications The HMC435MS8G is ideal for: * Basestation Infrastructure * MMDS & 3.5 GHz WLL * CATV/CMTS * Test Instrumentation Functional Diagram General Description The HMC435MS8G is a non-reflective DC to 4 GHz GaAs MESFET SPDT switch in a low cost 8 lead MSOP8G surface mount package with an exposed ground paddle. 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. On-chip circuitry allows positive voltage control of 0/+5 Volts at very low DC currents. 14 SWITCHES - SMT Electrical Specifications, TA = +25 C, Vctl = 0/+5 Vdc, 50 Ohm System Parameter Frequency DC - 2.5 GHz DC - 3.6 GHz DC - 4.0 GHz DC - 1.0 GHz DC - 2.0 GHz DC - 2.5 GHz DC - 3.6 GHz DC - 4.0 GHz DC - 2.5 GHz DC - 3.6 GHz DC - 4.0 GHz 0.5 - 4.0 GHz 0.5 - 4.0 GHz 0.5 - 1.0 GHz 0.5 - 2.5 GHz 0.5 - 4.0 GHz DC - 4.0 GHz tRISE, tFALL (10/90% RF) tON, tOFF (50% CTL to 10/90% RF) 40 60 ns ns 56 46 43 37 30 15 13 11 16 27 48 45 41 Min.
