One challenge of designing a dc-coupled biomedical radar sensor is dealing with the dc offset voltage presented in its receiver. The undesired dc offset is mainly caused by clutter reflection and hardware imperfection. It may saturate the baseband am

In this paper, we developed three designs of dual-band coupled-line couplers with wide separation between bands. Coupler A was constructed using three cascaded coupled-line sections with a band ratio $f_{H}/f_{L}$ of up to 7. Coupler B, with a stub-t

A common problem of biomedical radar sensors is the DC offset at the output of radar receiver front-end. In this paper, a DC-coupled Doppler radar sensor system with an analog DC offset calibration circuit is proposed. The calibration circuit can tra

A novel differential bandpass filter based on the cascaded parallel coupled lines is proposed, which takes the features of wide passband, high common-mode suppression and compact size. Six transmission zeros are created and located at the frequency r

A microstrip diplexer consisting of two new types of ring filters is presented in this letter. The proposed ring filter is able to move one of transmission zeros closer to its passband corner by connecting the feeding capacitors at the different loca

This paper describes design of a reconfigurable dual-band branch-line coupler, consisting of conventional dual-band coupler associated with new type of tuning networks for individually adjusting coupling coefficient at two operation frequencies. The
