IDT launches digital re-distortion demodulator

IDT is selling a digital pre-distortion (DPD) demodulator operating from 3,200MHz to 4,000MHz which enhances the performance of the digital pre-distortion transmitter linearisation path of cellular base stations.

With its integrated digital step attenuator (DSA) and single-pole-double-throw switch (SP2T), the F1358 DPD joins two other demodulators—the F1320, operating at 400MHz to 1200MHz, and the F1370, operating at 1,300MHz to 2,900MHz.

All of the DPD demodulators feature IDT’s patented ‘Zero-Distortion’ and ‘Glitch-Free’ technologies and are footprint-compatible.

The F1358 demodulator improves transmitter adjacent channel leakage ratio (ACLR) performance while reducing costs by eliminating the need for external IF amplifiers, baluns, switches and DSAs.

It reduces power consumption by over 1W compared to conventional solutions, and delivers high reliability with an intercept point of 42dBm up to 105 degrees operating temperature.

The device comes in a 6x6mm 36-VFQFPN package.
