HMC208MS8 MICROWAVE CORPORATION GaAs MMIC SMT DOUBLE-BALANCED MIXER 0.7 - 2.0 GHz FEBRUARY 2000 900 MHz Performance General Description ULTRA SMALL PACKAGE: MSOP8 The HMC208MS8 is an ultra miniature doublebalanced mixer in an 8 lead plastic surface mount Mini Small Outline Package (MSOP). This passive MMIC mixer is constructed of GaAs Schottky diodes and novel planar transformer baluns on the chip. The device can be used as a up, or downconverter, bi-phase (de)modulator or phase comparator for 900, 1500, or 1900 MHz applications. It is especially suited for miniature basestations, PCMCIA transceivers, cable modems, and portable wireless applications because of its high dynamic input signal range, small size, and zero DC bias requirement. The consistent MMIC performance will improve system operation and assure regulatory compliance. The MSOP8 package is the smallest footprint available for a complete doublebalanced 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.
