Broadband differential input RF amp for simpler integrated transceiver-based designs
F1423 integrates a high-performance amplifier and balun in one package, providing a differential input that aligns with the standard differential Tx outputs of RF DACs and integrated transceivers. Together with its wideband RF performance, this results in a much more streamlined transmitter design than competitive alternatives for today’s advanced wireless applications.
The F1423 delivers wide bandwidth – from 600 MHz to 3 GHz – to address a variety of RF transmitter applications with a single device. The amplifier delivers 13 dB typical gain, 20 dB Common-Mode-Rejection-Ratio (CMRR) and linearity of 42 dBm OIP3 @ 2000 MHz.
The F1423 features a 50Ω differential RF input and 50Ω single-ended output with up to 22 dBm of output power at 1 dB compression. It is suited for the high crest factor, high bandwidth, complex modulated 2G, 3G, and 4G signals that are output from RF DACs and integrated transceivers. It operates with a single 5 V supply at a typical supply current of 120 mA. In a 4 x 4 mm 24-QFN package it costs $3.17 (10,000).
