摘要

In this article, novel single- and dual-band reconfigurable microwave component (RMC) designs with very compact circuit sizes are proposed, which can be reconfigured into multiple functions, including a bandpass filter, a bandstop filter, and a quadrature coupler. The proposed RMCs with filter and coupler functions are based on lumped elements and transistor-based switches such that they are very suitable for on-chip implementation. Specifically, the proposed 10-GHz RMC in GaAs can achieve the functions of a bandpass filter, a bandstop filter, and a quadrature coupler with a circuit size of only 1.8 mm × 1.35 mm. On the other hand, the proposed 9.5/24-GHz RMC in GaAs can be reconfigured as either a dual-band bandpass filter or a dual-band quadrature coupler, while the circuit size is only 1.36 mm × 1.15 mm. In addition, to demonstrate the possible application of the proposed RMC designs, a proof-of-concept 2.45-GHz radar system prototype based on a proposed 2.45-GHz RMC is implemented in PCB, which successfully integrates the functions of target speed detection and transmission in a single hardware.
