TQP3M9028 High Linearity LNA Gain Block Product 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 1.8 dB Noise Figure while only drawing 85 mA SOT-89 Package current. The device is housed in a leadfree/green/RoHS- compliant industry-standard SOT-89 package. Product Features The TQP3M9028 has the benefit of having excellent gain 50-4000 MHz flatness across a broad range of frequencies. The low noise Flat gain (14.7 0.3 dB) from 0.5 3.5 GHz figure and high linearity performance allows the device to +40 dBm Output IP3 be used in both receiver and transmitter chains for high 1.8 dB Noise Figure 1900 MHz performance systems. The amplifier is internally matched No RF components needed 50 Ohm Gain Block using a high performance E-pHEMT process and only requires an external RF choke and blocking/bypass Unconditionally Stable capacitors for operation from a single +5V supply. The +5V Single Supply, 85 mA Current internal active bias circuit also enables stable operation SOT-89 Package over bias and temperature variations. The TQP3M9028 covers the 50-4000 MHz frequency band and is targeted for wireless infrastructure or other applications requiring high linearity and/or low noise figure.
