HMC436MS8G / 436MS8GE v04.0607 Typical Applications Features This switch is ideal for use as a DPDT Diversity or SP3T Switch for: DPDT or SP3T Functionality • HiperLAN & 802.11a WLAN High IP3: +52 dBm • WiMAX & Fixed Wireless High Input P0.1dB: +32 dBm • UNII Radios Positive Control: 0/+3V or 0/+5V • Mulit-beam Antenna Switching Optional ”All-Off” State Functional Diagram General Description Low Insertion Loss: 1.0 dB The HMC436MS8G & HMC436MS8GE are low cost C-band DPDT switches that operate 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 switch can also operate as a SP3T switch with any of the RF ports serving as the common port. 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.

Signal lines should have 50 ohm impedance while the package ground leads and exposed paddle should be connected directly to the ground plane similar to that shown above. A sufficient number of viaholes should be used to connect the top and bottom ground planes. The evaluation circuit board shown above is available from Hittite upon request.
