Abstract
— A reconfigurable matching network has been developed and it is based on loaded line techniques. It consists of8 switched MEMS capacitors producing 256 (2,) different impedances and is only 1x2.5 mm in size on a glass substrate. The network is ideally suited to match power amplifiers with 10-20 Ω Ω Ω Ω output impedance to 50-60 Ω Ω Ω Ω systems at 20-50 GHz. The estimated loss of the network is only 1-1.5 dB at 40 GHz while matching a 10-20 Ω Ω Ω Ω load ,to a ,50 Ω Ω Ω Ω load. The reconfigurable network can also be used as an impedance tuner in noise parameter and load-pull measurements of active devices at 30-65 GHz.
