How it works

According Electroschematics site describe the IDTF1370 is a digital pre-distortion demodulator (DPD) for power amplifiers linearization in BTS transmitter that utilize the IDT zero-distortion, and glitch-free technology that offers customers an unparalleled high-performance DPD demodulator. It utilizes the technique called pre-distortion, in digital communication it is used to improve the linearity of the transmitter performance by pre-distorting a data to counteract the distortion inherent in the power amplifier. The F1370 has an RF channel range of 1300-2900MHz, it’s IF frequency ranges 20-500MHz, a typical gain of 12.5dB, +41dBm IP3o, and a High/Low side injection. The device features an integrated DPD IC for MIMO, which eliminates the need for external IF amps, baluns, switches, and DSAs thus reduce solution cost and space significantly. It has a reduction of greater that 1-Watt power consumption compared to conventional solutions.
