IDT introduced a broadband differential input RF amplifier that greatly simplifies designs for transmitters utilising RF digital-to-analog converters (DACs) and/or integrated transceivers used in a wide variety of base stations and public safety infrastructure.
The F1423 is IDT’s latest RF offering which integrates a high-performance amplifier and balun in one small package, providing a differential input that aligns with the standard differential Tx outputs of RF DACs and integrated transceivers. Together with its excellent wideband RF performance, this results in a much more streamlined transmitter design than competitive alternatives for today’s advanced wireless applications.
Available in a 4mm x 4mm 24-QFN package, the F1423 delivers wide bandwidth from 600MHz to 3000MHz to address a variety of RF transmitter applications with a single device. Also, this high-performance amplifier delivers 13dB typical gain, 20 dB Common-Mode-Rejection-Ratio (CMRR) and very high linearity of 42 dBm OIP3 @ 2000MHz.
Operating with a single 5V supply at a typical supply current of 120 mA, the F1423 features a 50 ohm differential RF input and 50 ohm single-ended output with up to 22 dBm of output power at 1dB compression. It is ideally suited for the high-crest factor, high-bandwidth, complex modulated 2G, 3G, and 4G signals that are output from RF DACs and integrated transceivers.
