HMC488MS8G

v00.00503 MICROWAVE CORPORATION HMC488MS8G GaAs MMIC MIXER W/ INTEGRATED LO AMPLIFIER, 4.0 - 7.0 GHz Typical Applications The HMC488MS8G is ideal for: • UNII, ISM & WLAN • Point to Point/Multi-Point Radios • VSAT Features Conversion Loss: 7 dB Integrated LO Amplifier: 0 to +6 dBm Drive Input IP3: +15 dBm 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. 12 MIXERS - SMT Electrical Specifications, TA = +25° C, IF= 100 MHz, Vdd= 5V LO = +2 dBm Parameter Min.

Interface Schematic 1 LO 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 12 - 282 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 12 MIXERS - SMT List of Material Item J1 - J3 J4 - J5 C1 U1 PCB* Description PC Mount SMA RF Connector DC Pins 10,000 pF Chip Capacitor, 0603 Pkg.
