Summary: 
A matched filter (Mf) based on analog filter technology for DS-CDMA mobile radio is presented. An experimental one-chip LSI of AMF is developed for measuring various areas of performance such as power consumption, cut-off frequency, and linearity. The measurements show that power consumption is only 110mW at a voltage supply of 3V and an operational clock frequency of 25 MHz. We implemented a RAKE combiner using experimental AMF LSI and measured the bit error rate (BER) performance of DS-CDMA signal transmission in a multipath fading environment.
