| v00.0700 MICROWAVE CORPORATION HMC285 GaAs MMIC SMT SINGLE BALANCED MIXER, 1.7 - 3.5 GHz Typical Applications The HMC285 is ideal for: * PCS * W-CDMA * 2.4 GHz ISM * MMDS Features No External Components Required LO / RF Isolation: 30 dB Input IP3: +20 dBm Ultra Small SOT26 Package Functional Diagram General Description The HMC285 is an ultra miniature single balanced mixer in an 6 lead plastic surface mount SOT26 package. 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 consistent MMIC performance will improve system operation without the need for external components. The SOT26 package is the smallest footprint available for a complete single-balanced mixer, 0.118" x 0.118" (3.0mm x 3.0mm). 12 MIXERS - SMT Electrical Specifications, TA = +25 C, As a Function of IF Frequency Parameter Min.
