Gain State Fully Internally Matched Module Integrated Blocking Capacitors, Bias Inductors 3-wire SPI Control Programming General Description Pin Configuration The TQM879006A is a digital variable gain amplifier (DVGA) featuring high linearity over the entire gain control range. The amplifier module features the integration of a low noise amplifier gain block, a digitalstep attenuator (DSA), along with a high linearity ¼W 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 TM a serial periphery interface (SPI ). The TQM879006A features variable gain from 0 dB to 31.7 dB at 2 GHz, has +43 dBm Output IP3, and +24.5 dBm P1dB. The amplifier also has a very low 1.5 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 +5V supply and is available in a compact 28-pin 6x6 mm leadless SMT package.
