SPM-1045 Datasheet, PDF (1/8 Pages) List of Unclassifed Manufacturers – High Linearity Passive FET Mixer

Product Description
The Sirenza SPM-1045 is a passive mixer designed for
systems that require high linearity up- and down-conver-
sion. It employs proprietary silicon FETs with proven reli-
able core-and-wire baluns. It operates efficiently over a
wide range of Local Oscillator powers, with input third
order intercept remaining approximately 15-20 dB above
LO power. This product is packaged in a standard surface
mount module for excellent RF performance.
