TX Differential Input RF Amplifier GENERAL DESCRIPTION The F1423 is a 600 MHz to 3000 MHz TX differential input / single-ended output RF amplifier used in transmitter applications. The F1423 TX Amp provides 13.1 dB gain with +41.8 dBm OIP3 and 5.1 dB noise figure at 2000 MHz. This device uses a single 5 V supply and 120 mA of ICC. This device is packaged in a 4mm x 4mm, 24-pin Thin QFN with 50 ohm differential RF input and 50 ohm single ended RF output impedances for ease of integration into the signal-path. COMPETITIVE ADVANTAGE In typical Base Stations, RF Amplifiers are used in the TX traffic paths to drive the transmit power amplifier. The F1423 TX Amplifier offers very high reliability due to its construction using silicon die in a QFN package. The F1423 includes a broadband differential input to accept AC-coupled signals directly from a balanced modulator or RF DAC architecture.
