General Description
Pin Configuration
The TQP3M9008 is a cascadable, high linearity gain
block amplifier in a low-cost surface-mount package. At
1.9ꢀGHz, the amplifier typically provides 20.6ꢀdB gain,
+36ꢀdBm OIP3, and 1.3ꢀdB Noise Figure while only
drawing 85ꢀmA current. The device is housed in a lead-
free/green/RoHS-compliant industry-standard SOT-89
package using a NiPdAu plating to eliminate the
possibility of tin whiskering.

The TQP3M9008 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 +5ꢀV supply. The internal active
bias circuit also enables stable operation over bias and
temperature variations.
