Preliminary Data Sheet
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.
Product Specifications: Down-converter
Test Conditions: FLO = 750MHz FIF = 100MHz Frf = 850MHz Plo = 17dBm
