HMC272MS8 MICROWAVE CORPORATION GaAs MMIC SMT SINGLE BALANCED MIXER 1.7 - 3 GHz FEBRUARY 2001 Features General Description ULTRA SMALL PACKAGE: MSOP8 The HMC272MS8 is an ultra miniature single balanced mixer in an 8 lead plastic surface mount Mini Small Outline Package (MSOP). This passive MMIC mixer is constructed of GaAs Schottky diodes and a novel planar transformer balun on the chip. The RF port is balanced via the MMIC balun while the LO port is connected directly to the diodes. The device can be used as an up or downconverter for PCS, W-CDMA, 2.4 ISM, or MMDS applications. The consistent MMIC performance will improve system operation and assure regulatory compliance. The MSOP8 package is the smallest footprint available for a complete single-balanced mixer, 0.118” x 0.190” (3.0mm x 4.9mm). At a height of 0.040” (1.0mm) this is the thinnest mixer package available today.

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