IDT Launches New RF Device to Reduce Power Consumption of Cellular Base Stations

FREMONT, CA: Integrated Device Technology introduces F1358 integrated digital pre-distortion (DPD) demodulator, a new RF device to reduce power consumption, solution cost and board area for developers of TDD cellular base stations.

The IDT F1358 is a highly linear complex IF digital pre-distortion (DPD) demodulator with built-in digital step attenuator (DSA) and single-pole-double-throw switches (SP2Ts). 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.

The new RF device, operating from 3200 MHz to 4000 MHz, 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.

“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. It is an ideal, flexible solution for linearizing base transceiver station (BTS) transmitters for 3 to 4 GHz TDD systems,” said Chris Stephens, general manager, RF division, IDT.
