General Description
The TQL9048 is a cascadable, high linearity gain block
amplifier in a low-cost surface-mount package. At 1.9
GHz, the amplifier typically provides 14.5 dB gain,
+40.5 dBm OIP3, and 1.7 dB Noise Figure while only
drawing 130 mA current. The device is housed in a very
small 2x2 mm package.
The TQL9048 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 to maintain high
performance over temperature and integrates a shut-
down biasing capability to allow for operation for TDD
applications.
The TQL9048 covers the 50-4000 MHz frequency band
and is targeted for wireless infrastructure or other
applications requiring high linearity and/or low noise
figure.
