The TQP7M9104 is a 2W 5V high-linearity driver amplifier in a standard 4x4mm QFN surface-mount package. At 2.1 GHz, the TQP7M9104 offers 15.8 dB gain, 49.5 dBm OIP3, and +32.8 dBm of compressed 1dB power while drawing 427 mA current. Internal circuitry allows the amplifier to offer ‘Class A’ linearity performance with ‘Class AB’ efficiency. The TQP7M9104 contains added features implemented on-chip that differentiates it from other products in the market. The amplifier contains RF overdrive protection allowing the device to be very rugged. The internal active bias allows the amplifier to operate off of a 5V supply but also provides DC overvoltage protection which protects the amplifier from electrical DC voltage surges and high input RF input power levels that may occur in a system. The internal active bias circuit also allows for shut-down capability. The device is housed in a lead-free / green / RoHS-compliant, industry-standard 4x4mm QFN package. The device is ideal for 3G / 4G base station transceivers, repeaters, Defense & Aerospace applications, or any other general wireless application in the 400-4000 MHz frequency range requiring high linearity.
