General Description
The HMC351S8 & HMC351S8E are double balanced
mixers in 8 lead plastic surface mount packages.
The passive GaAs schottky diode mixer implements
planar on chip baluns and requires no external com-
ponents. The mixer can be used as an upconverter,
down converter, or modulator. The mixer provides 9
dB conversion loss and +25 dBm IIP3 with LO drive
levels of +19 dBm. The design was optimized for low
cost high volume applications where high converter
linearity is required. The high LO suppression of 42
dB yields excellent carrier suppression for modulator
applications.
