General Description
The HMC171C8 is a miniature double-balanced mixer in a non- hermetic ceramic
surface mount package that can be used as
an upconverter, downconverter or biphase
modulator. The device is a passive diode/
balun type mixer with high dynamic range.
Noise figure is essentially equal to the conversion loss. The mixer can handle larger
signal levels than most active mixers due to
the high third order intercept. MMIC implementation provides exceptional balance in
the circuit resulting in high LO/RF and LO/IF
isolations and unit-to-unit consistency. This
mixer has applications in circuits where
small size and surface mount compatibility
are important.
