TQM829007 数字可变增益放大器
The TriQuint TQM829007 is a digital variable gain amplifier (DVGA) featuring high linearity performance in a fully integrated module. The amplifier module features the integration of a low noise amplifier gain block, a digital-step attenuator (DSA) along with a high linearity 0.25 Watt amplifier. The module has the added features of integrating all matching components with bias chokes and blocking capacitors. The internal DSA offers 0.5 dB step, 6-bit and 31.5 dB range and is controlled with a serial periphery interface (SPITM). The TQM829007 features variable gain from 0 to 31.5 dB at 0.9 GHz, has +39.5 dBm Output IP3, and +24.3 dBm P1dB. The amplifier also has a very low 2.1 dB Noise Figure (at maximum gain) allowing it to be an ideal DVGA for both receiver and transmitter applications. The amplifier operates from a single +5 V supply and is available in a compact 28-pin 6 x 6 mm leadless surface mount package.
