Functional Diagram
General Description
The HMC488MS8G(E) is an ultra miniature double-
balanced 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.
