Comparison of Tunable Microwave Bandpass Filters

2018 11th International Symposium on Communication Systems, Networks & Digital Signal Processing (CSNDSP), 2018
The development of software-defined radio and Radio-over-Fiber solutions for the future 5G systems necessitates the availability of small, cost-effective and tunable microwave filters. Possibility of integration is another requirement. As variable capacitance diodes are lossy in the millimeter wave (mmW) region, other solutions are utilized, e.g ...

A tunable bandpass patch filter with varactors

2010 IEEE MTT-S International Microwave Symposium, 2010
This paper presents a miniaturized tunable bandpass patch filter using varactors. The filter is conceived with a triple-mode circular patch resonator with four slots, where the varactors were connected. The extracted equivalent model, the varactors assembly configuration and their biasing are presented.

Tunable reflectionless microstrip bandpass filters

2018 IEEE Radio and Wireless Symposium (RWS), 2018
A class of frequency-reconfigurable reflectionless microstrip bandpass filters is reported. This RF/microwave device is based on a complementary-duplexer architecture made up of a bandpass-type and a bandstop-type channel with resistive termination. Whereas the bandpass channel defines the transmission profile of the overall filter, the input-signal ...

Voltage tunable bandpass filter

2015 Signal Processing Symposium (SPSympo), 2015
A voltage tunable bandpass filter is presented. The filter is realized in microstrip technology using two stepped-impedance resonators. The voltage tuning is provided by means of varactor diodes. The filter has fixed absolute bandwidth of 30 MHz in the frequency range from 375 MHz to 915 MHz. The insertion loss is lower than 5 dB and return loss better
