®
Ultra Low-Noise, Flat Gain LNA
General Description
The QPL9503 is a flat-gain, high-linearity, ultra-low noise
amplifier in a small 2 x 2 mm surface-mount package. The
LNA provides a gain flatness of 2 dB (peak-to-peak) over a
wide bandwidth from 3 to 6 GHz. At 5.5 GHz, the amplifier
typically provides 21.6 dB gain, +35.5 dBm OIP3 at a 56mA
bias setting, and 0.95 dB noise figure. The LNA can be
biased from a single positive supply ranging from 3.3 to 5
volts. The device is housed in a green/RoHS-compliant
industry-standard 2x2 mm package.
The QPL9503 is internally matched using a high
performance E-pHEMT process and only requires five
external components for operation from a single positive
supply: an external RF choke and blocking/bypass
capacitors and a bias resistor going to pin 1. This LNA
integrates a shut-down biasing capability to allow for
operation in TDD applications.
The QPL9503 is optimized for linear performance across
the 3 to 6 GHz frequency band but can operate down to 600
MHz.
