The Sirenza Microdevices’ STM-1116 is a high linearity
active mixer for use in a wide variety of communication
systems covering the 800-1000 MHz frequency bands.
This device operates from a single 5V supply and provides
14 dB of conversion gain while requiring only 0dBm input
to the integrated LO driver. The STM-1116 also includes an
integrated on chip IF amplifier and is fabricated using Sili-
con Germanium (SiGe) device technology.
The RF and LO ports can be driven differential or single
ended. Each broadband port has been designed to mini-
mize performance degradation while operating into highly
reactive components such as SAW filters. The device is
packagedinan industrystandard16pin TSSOP with
exposed paddle for superb RF and thermal ground.
Test Conditions: TA = 25ºC, VCC =5.0V,
