IDT’s New Digital Pre-Distortion Demodulator Delivers Industry-Leading Performance for Cellular Base Stations
Operating in TDD Bands 42, 43, the F1358’s High Linearity and Level of Integration Can Reduce Cost, Area and Power Consumption
SAN JOSE, Calif., July 28, 2015—Integrated Device Technology, Inc. (IDT®) (NASDAQ: IDTI) 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 3200 MHz to 4000 MHz, 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 1300 MHz to 2900 MHz. 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 42 dBm up to 105 degrees operating temperature.
“Like its F1370 and F1320 predecessors for lower frequency bands, the F1358 digital pre-distortion demodulator delivers the gold standard in performance with a high integration level, reducing cost, area and power consumption for TDD RF developers,” said Chris Stephens, general manager of IDT’s RF division. “It is an ideal, flexible solution for linearizing base transceiver station (BTS) transmitters for 3 to 4 GHz TDD systems.
The F1358 digital pre-distortion demodulator is available now in a 6 x 6 mm 36-VFQFPN package.
