    Qorvo's TQL9047 is a cascadable, high linearity gain block amplifier in a low-cost surface mount package. At 1.9 GHz, the amplifier typically provides 14.5 dB gain, +35.5 dBm OIP3 and 1.6 dB Noise Figure while drawing 70 mA current from a 5V supply.

    The part features medium gain across a broad range of frequencies with the integration of a shut-down biasing capability to allow for operation for TDD applications. The low noise figure and high linearity performance allows the device to be used in both receiver and transmitter chains for high performance systems. The internal active bias circuit also enables stable operation over bias and temperature variations and can be biased from a single positive supply ranging from 3.3 to 5 volts. The amplifier is internally matched using a high performance E-pHEMT process and is housed in a small 2x2 mm surface-mount package.
