Qorvo's 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 digital-step attenuator (DSA), along with a high linearity 1/4 W amplifier. The module has the added features of integrating all matching components with bias chokes and blocking capacitors in a compact 6x6 mm leadless SMT package. The internal DSA offers 0.5 dB step, 6-bit, and 31.5 dB range and has a serial controlled interface. The DVGA operations over the entire 1.4 - 2.7 GHz frequency range with +43 dBm Output IP3 and +24.5 dBm P1dB while operating from single +5V supply. 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 device is ideal for 3G/4G base station transceivers or repeater applications. The TQM879006A is pin and package compatible to the TQM829007 0.6 - 1.0 GHz DVGA.
