TQM879006

1800 - 2700 MHz, 0.25 Watt Serial Controlled Digital Variable Gain Amplifier, 6-Bit, 0.5 dB Steps, Packaged

Qorvo's 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 (LNA) 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 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 +5 V supply and is available in a compact 28-pin 6 x 6 mm leadless surface mount package.
