Description

The Sirenza Microdevices' STQ-2016 is a direct quadrature modulator targeted for use in a wide range of communications systems, including cellular/PCS, CDMA2000, UMTS, and ISM datacom. This device features a wide 700-2500 MHz operating frequency band, excellent carrier and sideband suppression, and a low broadband noise floor.

The STQ-2016 uses silicon germanium (SiGe) device technology and delivers a typical output power of -11dBm with greater than 60dB IM3 suppression. A digital input shut-down feature is included that, when enabled, attenuates the output by 60dB. The device is packaged in an industry standard 16 pin TSSOP with exposed paddle for superb RF and thermal ground.
