The TQP3M9005 is a high linearity low noise gain block amplifier in a low-cost surface-mount package. At 1.9 GHz, the amplifier typically provides 15.3 dB gain, +34 dBm OIP3, and 0.8 dB Noise Figure while only drawing 50 mA current. The device is housed in a leadfree/green/RoHS-compliant industry-standard 16-pin 3x3mm QFN package.
The TQP3M9005 has the benefit of having high linearity while also providing very low noise across a broad range of frequencies. This allows the device to be used in both receive and transmit 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 supply. The internal active bias circuit also enables stable operation over bias and temperature variations.
The TQP3M9005 covers the 0.1 - 4 GHz frequency band and is targeted for wireless infrastructure or other applications requiring high linearity and/or low noise figure.
