Integrated Device Technology (IDT) has introduced a new RF device that greatly reduces power consumption, solution cost and board area for developers of TDD cellular base stations. The F1358, is an integrated digital pre-distortion (DPD) demodulator that operates from 3200 MHz to 4000 MHz to deliver high levels of linearity 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.
Operating in TDD Bands 42, 43, the F1358’s High Linearity and Level of Integration Can Reduce Cost, Area and Power Consumption. It is the 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.
