The switch is ideal for cellular/PCS/3G basestation applications yielding 50 to 60 dB isolation, low 0.8 dB insertion loss and +52 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 a single positive voltage control of 0/+5 Volts at very low DC currents. An enable input (EN) set to logic high will put the switch in an “all off” state. Features• High Isolation: 70 dB @ 1 GHz    57 dB @ 2 GHz• Single Positive Control: 0/+5V• +52 dBm Input IP3• Non-Reflective Design• All Off State• Ultra Small MS8G SMT Package: 14.8 mm²• Included in the   HMC-DK005 Designer’s KitTypical Applications• Basestation Infrastructure• MMDS & 3.5 GHz WLL• CATV/CMTS• Test InstrumentationFunctional Diagram 代理HITTITE全系列开关，欢迎订购：    HMC349MS8G    DC-4.0GHz 高隔离SPDT无反射开关    HMC393MS8G    5.0-6.0GHz DPDT差异开关    HMC427LP3    DC-8.0GHz 正相控制传输开关    HMC435MS8G    DC-4.0GHz 无反射开关    HMC436MS8G    4.9-5.9GHz DPDT差异开关    HMC446    824-894MHz 10W T/R开关    HMC484MS8G    DC-3.0GHz 10W T/R开关    HMC536MS8G    DC-6.0GHz 正相控制T/R开关    HMC546MS8G    0.2-2.2GHz 10W T/R开关    HMC358MS8G    5.8-6.8GHz VCOw/缓冲放大器    HMC384LP4    2.05-2.25GHz VCOw/缓冲放大器
