A low‐loss and well‐matched wideband microwave coaxial bias T is presented. A simple structure makes the bias T easy and low cost to design and fabricate. Test results demonstrate the excellent performance of the bias T. The measured return loss is better than 30 dB, and the insertion loss is close to 0.1 dB over awide frequency range. The 0.5 dB insertion loss bandwidth is 3–16 GHz. Furthermore, the RF isolation is more than 30 dB. © 2001 John Wiley & Sons, Inc. Microwave Opt Technol Lett 29: 236–238, 2001.
