TQL9047
High Linearity Gain Block
®
Product Overview
The TQL9047 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, +35.5 dBm
OIP3 and 1.6 dB Noise Figure while drawing 70 mA current
from a 5V supply.
The TQL9047 features medium gain across a broad range
of frequencies with the integration of a shut-down biasing
capability to allow for operation for TDD applications. The
low noise figure and high linearity performance allows the
device to be used in both receiver and transmitter chains
for high performance systems. The internal active bias
circuit also enables stable operation over bias and
temperature variations and can be biased from a single
positive supply ranging from +3.3 to +5 volts. The amplifier
is internally matched using a high performance E-pHEMT
process and is housed in a small 2ꢀxꢀ2 mm surface-mount
package.
