General Description
The TQP3M9009 is a cascadable, high linearity gain block
amplifier in a low-cost surface-mount package. At 1.9
GHz, the amplifier is targeted to provide 21.8 dB gain,
+39.5 dBm OIP3, and 1.3 dB Noise Figure while only
drawing 125 mA current. The device is housed in a
leadfree/green/RoHS-compliant industry-standard SOT-89
package using a NiPdAu plating to eliminate the
possibility of tin whiskering.
The TQP3M9009 has the benefit of having high gain
across a broad range of frequencies while also providing
very low noise. This allows the device to be used in both
receiver and transmitter chains for high performance
systems. The amplifier is internally matched using a high
performance E-pHEMT process and only requires an
external RF choke and blocking/bypass capacitors for
operation from a single +5V supply. The internal active
bias circuit also enables stable operation over bias and
temperature variations.
The TQP3M9009 covers the 0.05-4 GHz frequency band
and is targeted for wireless infrastructure or other
applications requiring high linearity and/or low noise
figure.
