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 8 Pin 2X2 mm DFN Package biased from a single positive supply ranging from 3.3 to 5 volts. The device is housed in a green/RoHS-compliant Product Features industry-standard 2x2 mm package. 0.6-6 GHz Operational Bandwidth The QPL9503 is internally matched using a high Ultra low noise figure, 0.95 dB NF 5.5 GHz performance E-pHEMT process and only requires five Bias adjustable for linearity optimization external components for operation from a single positive 35.5 dBm OIP3 at 65mA IDD supply: an external RF choke and blocking/bypass Shut-down mode pin with 1.8V TTL logic capacitors and a bias resistor going to pin 1. This LNA integrates a shut-down biasing capability to allow for Unconditionally stable operation in TDD applications. Integrated shutdown control pin Maintains OFF state with high Pin drive The QPL9503 is optimized for linear performance across +3V to +5V supply does not require -Vgg the 3 to 6 GHz frequency band but can operate down to 600 MHz.
