IDTF1358NBGI Datasheet DPD Demodulator for PA Linearization 3200 MHz to 4000 MHz FEATURES GENERAL DESCRIPTION Wide flat performance IF BW This document describes the specification for the Wide RF and LO BWs (~ 800 MHz) IDTF1358 Digital Pre-Distortion Demodulator for PA LO can be High or Low Side linearization. This series of devices is offered in 3 Ideal for Multi-Carrier Systems variants to cover common UTRA bands. Drives ADC directly COMPETITIVE ADVANTAGE Ultra linear +41 dBm OIP3 Excellent ACLR performance In typical basestation transmitters, digital pre-distortion 200 output impedance is employed to improve the Transmitter performance. Fully integrated DPD demodulator The signal coming out of the PA is sampled and the Standby Mode w/Fast Recovery incoming Tx chain I&Q data is pre-distorted to Current draw is 216 mA counteract the distortion inherent in the PA. The PA 6 x 6 mm 36 pin package signal is adjusted via a digital step attenuator to a lower level and then sub-sampled at an IF frequency of ~200 MHz which necessitates the need for a highly linear FUNCTION BLOCK DIAGRAM demodulator to downmix to quadrature IF from the Transmit frequency. By sampling IF I and IF Q independently and then digitally combining these signals, TMTM Zero-Distortion Zero-Distortion TMTM an effective doubling of the sample rate can be achieved. GlitGlitchch--FreFreee CLK Any distortion in this path will degrade the performance DATA SPI DEC IFI CSb of the DPD algorithm. By utilizing an ultra-linear demodulator w/integrated DSA such as the IDTF1358, STBY the ACLR and/or power consumption of the full Tx Bias I SET Ctrl 2 system can be improved significantly.
