MICROWAVE CORPORATION HMC296MS8 v02.1201 LOW LO DRIVE DOUBLE-BALANCED FET MIXER, 1.1 - 1.7 GHz Typical Applications Features The HMC296MS8 is ideal for: IP3 (Input): +24 dBm @ +11 dBm LO • Miniature Basestations LO Range = +3 to +11 dBm • PCMCIA Conversion Loss: 7 dB • Portable Wireless LO/RF Isolation: 40 dB • WirelessLAN Functional Diagram General Description The HMC296MS8 is a low LO drive, high IP3 double-balanced FET mixer in an 8 lead plastic surface mount MSOP package. This MMIC mixer is constructed of switched GaAs FETs and novel planar transformer baluns on the chip. The device can be used as an up or downconverter for 1.1 to 1.7 GHz applications. The consistent MMIC performance will improve system operation. The package dimensions are 0.118” x 0.192” (3.0mm x 4.9mm).

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. A sufficient number of VIA holes should be used to connect the top and bottom ground planes. The evaluation circuit board shown is available from Hittite upon request.
