General Description

The TQL9062 is a cascadable high-linearity gain block

amplifier in a small 2 x 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.
