RFMD’s 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 700MHz to 2500MHz 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 typical 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.
