1 v3.68 Typical Applications Features The HMC488MS8G / HMC488MS8GE is ideal for: Basestations & Repeaters Access Points & Subscribers UNII, ISM, WLAN & WiMAX Point to Point/Multi-Point Radios VSAT Radio Functional Diagram Low Conversion Loss: 7 db Double-Balanced Topology Integrated LO Amplifi er: to +6 dbm Drive Input IP3: +15 dbm Single Supply: 46 ma MSOP8-G Package: 14.8 mm 2 General Description Electrical Specifications, T A = +25 C, IF= 1 MHz, Vdd= 5V Parameter LO = The HMC488MS8G(E) is an ultra miniature doublebalanced mixer with integrated LO amplifi er 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 amplifi er can be driven from to +6 dbm and requires a single supply of 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. LO = dbm Min. Typ. Max.

An external RF bypass capacitor (1, pf) is required. 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 4 ma of current or failure may result. This pin is DC coupled and matched to 5 Ohms. One Technology Way, P.O.
