D a t a S h e e t . n e t / General Description The TQM879006 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 a serial periphery interface (SPITM). The TQM879006 features variable gain from -0.5 to 31dB at 2 GHz, has +41.3 dBm Output IP3, and +25.4 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. Pin Config...
