General Description
The HMC175MS8 & HMC175MS8E are miniature
double-balanced mixers in 8-lead plastic surface
mount Mini Small Outline Packages (MSOP). The
device can be used as an upconverter or downcon-
verter. The mixer provides exceptional isolation and
Intermodulation performance for applications in high
signal density environments. This device can also
be used as a biphase modulator or demodulator.
The MSOP8 is the smallest footprint available for a
complete double-balanced mixer (0.118” x 0.190” x
0.040”).
Electrical Specifications, TA = +25° C, LO Drive = +13 dBm
