Qorvo's TQL9093 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 1.5 to 4 GHz. At 2.6 GHz, the amplifier typically provides 20 dB gain, +41.5 dBm OIP3 at a 120 mA bias setting, and 0.7 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 2 x 2 mm package.
The TQL9093 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 TQL9093 is optimized for linear performance across the 1.5 to 4.2 GHz frequency band but can operate down to 600 MHz.
