Digital pre-distortion demodulator

29th July 2015


Integrated Device Technology Inc (IDT) introduced today a new RF device that greatly reduces power consumption, solution cost and board area for developers of TDD cellular base stations.

Operating from 3200MHz to 4000MHz, the F1358 integrated digital pre-distortion (DPD) demodulator delivers the industry’s highest levels of linearity and integration to enhance the performance of the digital pre-distortion transmitter linearization path of cellular base stations.

With its integrated digital step attenuator (DSA) and single-pole-double-throw switch (SP2T), this latest addition to IDT’s growing RF portfolio joins two other popular high-performance demodulators—the F1320, operating at 400 MHz to 1200 MHz, and the F1370, operating at 1300MHz to 2900MHz. 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 1 Watt compared to conventional solutions, and delivers high reliability with an intercept point of 42dBm up to 105 degrees operating temperature.

The F1358 digital pre-distortion demodulator is available now in a 6 x 6 mm 36-VFQFPN package.
