STQ-3016

Advanced Data Sheet Product Description The Stanford Microdevices’ STQ-3016 is a direct quadrature modulator targeted for use in a wide range of communications systems. This device features a wide 2500-4000 MHz operating frequency band, excellent carrier and sideband suppression, and a low broadband noise floor. The STQ-3016 uses silicon germanium device technology and delivers a typical output power of -13dBm with 50dB IM3 suppression. A shutdown feature is included that, when enabled, attenuates the output by 60dB.
