Abstract

As millimeter wave (MMW) electronic technologies have matured, MMW receiver research is also in the rapid development which includes front-end and frequency synthesizer. They all needed isolation between RF and DC bias. The good design bias T which can realize high isolation between DC bias source port and RF ports is necessary. In this paper, two new reduced-sized broad-band resonators are introduced which can be used in the active circuits. Their bandwidths are controllable and the performance of one bias T is better than the same size of the compact bias T whose size reduction is 55.55% of the conventional radial stubs. Its improvement of S11, S12, and S13 is 18.8, 8.2, and 28.3% respectively. The performance of another kind bias T has a slightly inferior, but it has good stop-band characteristic at 2 GHz and 8 GHz where the 4 GHz signal is needed. The two kinds of bias T perform as expected and the results are in good agreement with the simulated results, and have been used in the front-end circuit of our BHU-2D-U passive MMW imaging system.
