QPA9127 High Linearity Gain Block

Qorvo QPA9127 cascadable, high linearity gain block amplifiers come in a low-cost surface mount package. At 3.5 GHz, the amplifier provides 20 dB gain, +35 dBm OIP3, and 1.4 dB noise figure while drawing 70 mA current from a 5 V supply.

With the integration of a shutdown biasing capability to allow for the operation of TDD applications, the QPA9127 provides very flat gain across a broad range of frequencies. The low noise figure and high linearity performance allow 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 V to +5 V. The amplifier is internally matched using a high-performance E-pHEMT process and is housed in a small 2.0 mm x 2.0 mm surface-mount package.

The QPA9127 covers the 1 GHz to 6 GHz frequency band and is targeted for wireless infrastructure or other applications requiring high linearity and/or low noise figure.
