Introduction

The TQL9062 is a cascadable high-linearity gain block amplifier in a small 2×2 mm surface-mount package. At 3.5 GHz, the amplifier typically provides 16.3 dB gain, +43.6 dBm OIP3 at a 120 mA bias setting, and 1.4 dB noise figure. The LNA can be biased from a single positive supply ranging from 3.3 to 5 volts. The TQL9062 has good noise figure and high linearity performance allowing the device to be used in both receiver and transmitter chains for high performance systems. The gain block is internally matched using a high performance E-pHEMT process and only requires four external components for operation from a single positive supply: an external RF choke and blocking/bypass capacitors. This low noise amplifier contains an internal active bias circuit to maintain high performance over temperature and integrates a shut-down capability to allow for operation in TDD applications. The TQL9062 covers the 500 - 6000 MHz frequency band and is targeted for wireless infrastructure or other applications requiring high linearity and/or low noise figure.
