EDA Software Improves Accuracy Of Microstrip Filter Designs

摘要

The simulation and optimization of microstrip coupled-tine filters for WCDMA are quick and simple by using a popular EDA package.rnResearch work has focused recently on the development of wideband-code-division-multiple-access (WCDMA) mobile-communication systems throughout the world. RF filters are important components in wcdma base-station transceivers (BTS) to reject unwanted signals. In an RF receiver (Rx), a filter is generally required between the low-noise amplifier (LIMA) and the downconverter to rejectrnimage noise. In an RF transmitter (Tx), a filter is also required after the upcon-verter to reject image spurs, local-oscillator (LO) leakage, and other unwanted signals.
