Preliminary
Product Description
STM-1116
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.
800 - 1000 MHz High Linearity
Active Transmit Mixer
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
packaged in an industry standard 16 pin TSSOP with
exposed paddle for superb RF and thermal ground.
