The TQP3M9038 is a high linearity low noise gain block amplifier in a low-cost surface-mount package. It operates at frequencies between 50 and 400 MHz with a 2 dB noise figure and has a gain of 14.9 dB. The TQP3M9038 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 +5V supply. The internal active bias circuit also enables stable operation over bias and temperature variations. The device is housed in a lead free/green/RoHS-compliant industry-standard 3x3mm package.
