HMC488MS8G v00.00503 MICROWAVE CORPORATION GaAs MMIC MIXER W/ INTEGRATED LO AMPLIFIER, 4.0 - 7.0 GHz Typical Applications Features The HMC488MS8G is ideal for: Conversion Loss: 7 dB • UNII, ISM & WLAN Integrated LO Amplifier: 0 to +6 dBm Drive • Point to Point/Multi-Point Radios Input IP3: +15 dBm • VSAT Single Positive Supply: 5V @ 46 mA Functional Diagram General Description The HMC488MS8G is an ultra miniature doublebalanced mixer with an integrated LO amplifier in an 8 lead plastic SMT MSOP 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.

ALL GROUND LEADS AND GROUND PADDLE MUST BE SOLDERED TO THE PCB RF GROUND Pin Descriptions Pin Number Function Description 1 LO This pin is AC coupled & matched to 50 Ohm from 4.0 to 7.0 GHz. 2, 6, 7 GND This pin must be connected to RF ground. 3, 4 Vdd These pins are power supply for LO amp. An external RF bypass capacitor (10,000 pF) is required. 5 IF Port This pin is DC coupled. For applications not requiring operation to DC this port should be DC blocked externally using a series capacitor. Choose value of capacitor to pass IF frequency desired. For operation to DC, this pin must not sink/source more than 40 mA of current or failure may result. 8 RF Port This pin is DC coupled & matched to 50 Ohm from 4.0 to 7.0 GHz Interface Schematic For price, delivery, and to place orders, please contact Hittite Microwave Corporation: 12 Elizabeth Drive, Chelmsford, MA 01824 Phone: 978-250-3343 Fax: 978-250-3373 Order Online at www.hittite.com v00.0503 MICROWAVE CORPORATION HMC488MS8G GaAs MMIC MIXER W/ INTEGRATED LO AMPLIFIER, 4.0 - 7.0 GHz Evaluation PCB MIXERS - SMT 12 List of Material Item Description J1 - J3 PC Mount SMA RF Connector J4 - J5 DC Pins C1 10,000 pF Chip Capacitor, 0603 Pkg.
