QPL9503

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.

8 Pin 2X2 mm DFN Package

Product Features

 0.6-6 GHz Operational Bandwidth

 Ultra low noise figure, 0.95 dB NF @ 5.5 GHz

 Bias adjustable for linearity optimization

 35.5 dBm OIP3 at 65mA I_DD

 Shut-down mode pin with 1.8V TTL logic

 Unconditionally stable

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.

 Integrated shutdown control pin

 Maintains OFF state with high Pin drive

 +3V to +5V supply; does not require -Vgg

The QPL9503 is optimized for linear performance across

the 3 to 6 GHz frequency band but can operate down to 600

MHz.
