HMC208MS8
GaAs MMIC SMT DOUBLE-
BALANCED MIXER, 0.7 - 2.0 GHz
Features
Ultra Small Package: MSOP8
Conversion Loss: 9 dB
LO / RF Isolation: 24 dB
IP3 (Input): +17 dBm
General Description
The HMC208MS8 is an ultra miniature doublebalanced mixer in an 8 lead plastic surface mount
package (MSOP). This passive MMIC mixer is
constructed of GaAs Schottky diodes and novel
planar transformer baluns on the chip. The device
can be used as an upconverter, downconverter,
biphase (de)modulator, or phase comparator.
The consistent MMIC performance will improve
system operation and assure regulatory compliance.
