v01.0702 MICROWAVE CORPORATION HMC436MS8G GaAs MMIC DPDT DIVERSITY SWITCH, 4.9 - 5.9 GHz Typical Applications Features This switch is ideal for use as a DPDT Diversity Switch for 4.9 - 5.9 GHz applications: Low Insertion Loss: 1.0 dB • HiperLAN & 802.11a WLAN P1dB Compression: 1 Watt • UNII Radios Positive Control: 0/+3V High IP3: +50 dBm Ultra Small MSOP8G Package: 14.8 mm2 Functional Diagram The HMC436MS8G is a low cost C-band DPDT switch that operates between 4.9 and 5.9 GHz. This switch can operate as an integrated antenna diversity and transmit/receive switch for the 802.11a/HiperLAN and UNII radio platforms. The design provides 20 dB of isolation between antennas and between Tx and Rx ports. The switch features 1 dB insertion loss and high power handling capability. Switch state is controlled using four control voltage lines toggled between 0 and +3 to +5V. 14 SWITCHES - SMT General Description Electrical Specifications, TA = +25° C, Vctl = 0/+3 Vdc (Unless Otherwise Stated), 50 Ohm System Parameter Frequency Typ.
