HMC488MS8G / 488MS8GE v03.0608 Typical Applications Features The HMC488MS8G / HMC488MS8GE is ideal for: Low Conversion Loss: 7 dB • Basestations & Repeaters Double-Balanced Topology • Access Points & Subscribers Integrated LO Amplifier: 0 to +6 dBm Drive • UNII, ISM, WLAN & WiMAX Input IP3: +15 dBm 9 • Point to Point/Multi-Point Radios Single Supply: +5V @ 46 mA • VSAT Radio MSOP8-G Package: 14.8 mm2 MIXERS - DBL-BAL - SMT GaAs MMIC MIXER W/ INTEGRATED LO AMPLIFIER, 4 - 7 GHz Functional Diagram General Description The HMC488MS8G(E) is an ultra miniature doublebalanced mixer with integrated LO amplifier in an 8 lead plastic SMT MSOP8-G covering 4 - 7 GHz. This passive MMIC mixer integrates a GaAs Schottky diode quad, transformer baluns and a LO buffer on a single chip yielding a low conversion loss of 7 dB coupled with an input IP3 of +15 dBm. The LO buffer amplifier can be driven from 0 to +6 dBm and requires a single supply of +5V @ 46 mA. The device can be used as an upconverter, downconverter or bi-phase (de)modulator for a variety of point-to-point/ multipoint, VSAT, telemetry or broadband WLAN applications.
