Design and Fabrication of RF Receiver Module for IMT-2000 Handset
IMT-2000 단말기용 RF 수신모듈 설계 및 제작
Abstract
In this paper, we describes RF receiver module for IMT-2000 handset with 5MHz channel bandwidth. The fabricated RF receiver module consists of Low Noise Amplifier-, RF SAW filter, Down-converter, IF SAW filter, AGC and PLL Synthesizer. The NF and IIP3 of LNA is 0.8㏈, 3㏈m at 2.14㎓, conversion gain of downconverter is l0㏈, dynamic range of AGC is 80㏈, and phase noise of PLL is -100 ㏈m, at 100KHz. The receiver sensitivity is -110㏈m, adjacent channel selectivity is -48㏈m.
