Qorvo's TQP3M9028 is a cascadable, high linearity gain block amplifier in a low-cost surface mount package. At 1.9 GHz, the amplifier typically provides 14.7 dB gain, +40 dBm OIP3 and 2 dB Noise Figure while only drawing 85 mA current. The device is housed in a lead-free / green / RoHS compliant industry-standard SOT-89 package.
The part features excellent gain flatness across a broad range of frequencies. 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 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 +5 V supply. The internal active bias circuit also enables stable operation over bias and temperature variations.
The TQP3M9028 covers the 0.05 to 4 GHz frequency band and is targeted for wireless infrastructure or other applications requiring high linearity and/or low noise figure.
