At 1.9 GHz, the amplifier typically provides 20 dB gain, +36 dBm OIP3, and 1.3 dB Noise Figure while only drawing 85 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 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 +5V supply. The internal active bias circuit also enables stable operation over bias and temperature variations. The TQP3M9008 covers the 0.05-4 GHz frequency band and is targeted for wireless infrastructure or othe...
