Abstract

A multi-mode reconfigurable digital intermediate frequency (IF) module for software defined radio (SDR) transmitters is presented. It supports variable input sample rate from 7kHz to 30.72MHz, and variable signal bandwidth from 5kHz to 20MHz. Its output sample rate is 80MHz or 160MHz.The digital IF module consists of 7 half-band filters, a digital up converter (DUC) and 4 FIR filters. Each stage can be turned off separately. The 10-bit output signal to noise and distortion ratio (SNDR) is above 54.5dB, while the 12-bit input signal SNDR is 60dB.This digital IF module supports both traditional narrowband industry-specific network and LTE cluster communication applications.
