HMC272MS8
GaAs MMIC SMT SINGLE
BALANCED MIXER, 1.7 - 3 GHz
Features
Ultra Small Package: MSOP8
LO / RF Isolation: 32 dB
IP3 (Input): +20 dBm
General Description
The HMC272MS8 is an ultra miniature single balanced mixer in an 8 lead plastic surface mount
Mini Small Outline Package (MSOP). This passive MMIC mixer is constructed of GaAs Schottky
diodes and a novel planar transformer balun on
the chip. The RF port is balanced via the MMIC
balun while the LO port is connected directly to
the diodes. The consistent MMIC performance
will improve system operation and assure regulatory compliance.
