Ultra-low-noise, flat gain LNA
The TQL9092 provides a gain flatness of 2 dB (peak-to-peak) over a wide bandwidth—from 1.5 to 3.6 GHz. At 2.6 GHz, the amplifier typically provides 22.6 dB gain, +37 dBm OIP3 at a 65 mA bias setting, and 0.6 dB noise figure. The LNA can be biased from a single positive supply ranging from 3.3 to 5 V. It is offered in a 2 mm x 2 mm surface-mount package.
The TQL9092 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. It is also suitable for FDD systems, repeater/DAS, mobile infrastructure, LTE/WCDMA/CDMA/GSM, and general purpose wireless applications.
The TQL9092 is optimized for linear performance across the 1.5 to 4.2 GHz frequency band but can operate down to 600 MHz.
According to Qorvo, additional key features of the TQL9092 include >20 dB gain across 1.5 to 3.8 GHz, +37 dBm OIP3 at 65mA IDD, shut-down mode pin with 1.8V TTL logic, unconditionally stable, maintains OFF state with high Pin drive, and +3V to +5V supply; does not require -Vgg.
