SPM-2045 Datasheet, PDF (1/9 Pages) Stanford Microdevices – High Linearity Passive FET Mixer

Product Description
The Sirenza SPM-2045 is a passive mixer designed for
systems that require high linearity down- or up-conversion.
It employs proprietary silicon FETs with proven reliable
core-and-wire baluns. It operates efficiently over a wide
range of Local Oscillator powers, with input third order
intercept remaining approximately 15-18 dB above LO
power over this range. This product is packaged in a stan-
dard surface mount module for excellent RF performance.
