Abstract
This paper presents a new tunable Impedance Matching Network (IMN) structure in frequency range of 23.4-31.9GHz for wideband fifth generation (5G) Power Amplifiers (PAs) by using RF-MEMS switches. In this IMN, to adjust the impedance in the central frequencies of the 5G, i.e. 26 and 28 GHz, voltage is applied to the switch. Simulation results show that S(1,1) is −67.8 dB for 26GHz and −43.8 dB for 28 GHz. In frequency range of 24.5-28.8 GHz, S(1,1) is always less than −10dB. Electrical and mechanical simulations in the Advance Design System (ADS) and COMSOL simulation software indicate the IMN's ability to adjust impedance for center frequencies.
