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.

[1] Reference this number when ordering complete evaluation PcB [2] circuit Board Material: Rogers 4350 [3] these optional resistors will provide isolation between the Dc and RF circuitry.
the circuit board used in the final application should use RF circuit design techniques. 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.
