®
0.6
- 2.8 GHz High Linearity Pre-Driver
Product Overview
The QPA9442 is a wideband, high linearity driver amplifier. With optimized tuning, this device can provide up to 19dB of gain and achieve an output P1dB of 1W. The amplifier can provide excellent linearity performance with +46dBm output 3rd order intercept (OIP3), making it perfectly suited for 5G base station applications.
The QPA9442 is tunable over all cellular bands in the entire operating frequency band of 0.6
- 2.8 GHz and incorporates a shut-down function through the VPD pin.
The QPA9442 is housed in a 20-pin 4X4mm SMT package.
