HMC285 / 285E v02.0907 GaAs MMIC SMT SINGLE BALANCED MIXER, 1.7 - 3.5 GHz Features The HMC285 / HMC285E is ideal for: No External Components Required • PCS LO / RF Isolation: 30 dB • W-CDMA Input IP3: +21 dBm • 2.4 GHz ISM Ultra Small SOT26 Package 9 • MMDS MIXERS - SGL-BAL - SMT Typical Applications Functional Diagram General Description The HMC285 & HMC285E are ultra miniature single balanced mixers in 6 lead plastic surface mount SOT26 packages. 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 x 3 mm).
