TQP3M9028 Applications       High Linearity LNA Gain Block Repeaters Mobile Infrastructure Defense/Aerospace LTE / WCDMA / EDGE / CDMA General Purpose Wireless IF amplifier, RF driver amplifier SOT-89 Package Product Features         50-4000 MHz Flat gain (14.7 ± 0.3 dB) from 0.5 – 3.5 GHz +40 dBm Output IP3 2 dB Noise Figure @ 1.9 GHz No RF component needed; 50 Ω gain block Unconditionally stable +5V Single Supply, 85 mA Current SOT-89 Package Functional Block Diagram GND 4 1 RF IN 2 GND 3 RF OUT General Description The 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 leadfree/green/RoHS-compliant industry-standard SOT-89 package. The TQP3M9028 has the benefit of having 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 +5V supply. The internal active bias circuit also enables stable operation over bias and temperature variations. The TQP3M9028 covers the 0.05-4 GHz frequency band and is targeted for wireless infrastruct...
