Qorvo TQL9093 Ultralow Noise Flat Gain LNA
Qorvo TQL9093 Ultra Low Noise Flat Gain Low Noise Amplifier (LNA) is a high-linearity amplifier with a 2dB gain flatness (peak-to-peak) over a wide 1.5GHz to 4.0GHz bandwidth. The amplifier typically provides 20dB gain at 2.6GHz, +41.5 dBm OIP3 at a 120mA bias setting and 0.6dB noise figure. The LNA can be biased from a single positive supply ranging from 3.3V to 5.0V.
The TQL9093 is internally matched using a high performance E-pHEMT (Enhancement-Mode Pseudomorphic High-Electron Mobility Transistor) process and only requires five external components for operation from a single positive supply, an external RF choke, blocking/bypass capacitors, and a bias resistor going to pin 1. This LNA integrates a shut-down biasing capability to allow for operation in Time Division Duplex (TDD) applications.
The TQL9093 is optimized for linear performance across the 1.5GHz to 4.2GHz frequency band but can operate down to 600MHz.
The Qorvo TQL9093 Ultralow Noise Flat Gain LNA is available in a compact 2.0mm x 2.0mm Dual Flat No-Lead (DFN) package, ideal for space-constrained applications.
