Abstract

Based on the design and improvement of traditional hairpin microstrip bandpass filter, a cross-hairpin bandpass filter is designed in this paper. The filter is used in WCDMA operating between 1920GHz and 1980GHz. This paper analyzes the filters consisting of two hairpin resonators of differential coupling structures and their 3D models are simulated using Momentum based on ADS. Comparison of simulation and test results show that the improved filter has good passband and stopband characteristics.
