| v01.0702 MICROWAVE CORPORATION HMC436MS8G GaAs MMIC DPDT DIVERSITY SWITCH, 4.9 - 5.9 GHz Features Low Insertion Loss: 1.0 dB High IP3: +50 dBm P1dB Compression: 1 Watt Positive Control: 0/+3V Ultra Small MSOP8G Package: 14.8 mm2 Typical Applications This switch is ideal for use as a DPDT Diversity Switch for 4.9 - 5.9 GHz applications: * HiperLAN & 802.11a WLAN * UNII Radios Functional Diagram General Description 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 Electrical Specifications, TA = +25 C, Vctl = 0/+3 Vdc (Unless Otherwise Stated), 50 Ohm System Parameter Insertion Loss Frequency 4.9 - 5.1 GHz 5.1 - 5.9 GHz 4.9 - 5.1 GHz 5.1 - 5.4 GHz 5.4 - 5.9 GHz 4.9 - 5.1 GHz 5.1 - 5.4 GHz 5.4 - 5.9 GHz Vctl= 0/+3V Vctl= 0/+5V Vctl= 0/+3V Vctl= 0/+5V Vctl= 0/+3V Vctl= 0/+5V 4.9 - 5.9 GHz 14 16 20 17 16 13 27 30 23 29 47 49 Min.

HMC436MS8G DPDT Diversity Switch 103037 Evaluation PCB 1.5" x 1.5" 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 VIA holes should be used to connect the top and bottom ground planes. The evaluation circuit board shown above is available from Hittite upon request. * Circuit Board Material: Rogers 4350 For price, delivery, and to place orders, please contact Hittite Microwave Corporation: 12 Elizabeth Drive, Chelmsford, MA 01824 Phone: 978-250-3343 Fax: 978-250-3373 Order Online at www.hittite.com |
