Overview: TQP3M9018 ® High Linearity LNA Gain Block Product Overview
The TQP3M9018 is a cascade-able, high linearity gain block amplifier in a low-cost surface-mount package. At 1.9 GHz, this amplifier typically provides 20.5 dB gain, +37 dBm output IP3 and 1.3 dB noise figure while only drawing 85 mA current. The device is housed in a lead-free / green / RoHScompliant industry-standard 16-pin 3x3mm QFN package.
The TQP3M9018 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 requires only an external RF choke and blocking/bypass capacitors for operation from a single +5 V supply. The internal active bias circuit also provides stable operation over bias and temperature variations.
The TQP3M9018 covers the 0.02-4 GHz frequency band and is targeted for wireless infrastructure or other applications requiring high linearity and/or low noise figure.
