F1423 Datasheet TX Differential Input RF Amplifier 600 MHz to 3000 MHz GENERAL DESCRIPTION FEATURES The F1423 is a 600 MHz to 3000 MHz TX differential Broadband 600 MHz 3000 MHz input / single-ended output RF amplifier used in 13.1 dB typical gain 2000 MHz transmitter applications. 5.1 dB NF 2000 MHz +41.8 dBm OIP3 2000 MHz The F1423 TX Amp provides 13.1 dB gain with +21.5 dBm output P1dB 2000 MHz +41.8 dBm OIP3 and 5.1 dB noise figure at 2000 MHz. Single 5 V supply voltage This device uses a single 5 V supply and 120 mA of I . CC I = 120 mA CC This device is packaged in a 4mm x 4mm, 24-pin Thin Up to +105 C T operating temperature CASE QFN with 50 ohm differential RF input and 50 ohm 50 differential input impedance single ended RF output impedances for ease of 50 single ended output impedance integration into the signal-path. Positive gain slope for board loss compensation Standby mode for power savings 4 mm x 4 mm, 24-pin TQFN package COMPETITIVE ADVANTAGE In typical Base Stations, RF Amplifiers are used in the TX traffic paths to drive the transmit power amplifier. FUNCTIONAL BLOCK DIAGRAM 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.

Stresses above those listed above may cause permanent damage to the device. Functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
