For designs where tuner-diode matching is critical and space is limited, the ZMDC831BTA and 832BTA dual common-cathode, hyperabrupt varactor diodes report high tolerance C-V characteristics, inherent ...
Abstract: In this work, a frequency reconfigurable wearable antenna incorporating a varactor diode is proposed. The antenna is designed using a Felt substrate, chosen for its lightweight, flexible, ...
How does a varactor diode work? To form the PN junction that makes a diode, half the piece is doped with a trace amount of “donor atoms” that have one more electron than the intrinsic stuff to make ...
Abstract: This article proposes a conformal miniaturized varactor-tunable bandpass frequency selective surface (FSS) with stable transmission responses. First, the design principles for achieving low ...
Varactor (or “varicap”) diodes are used primarily in radio-frequency (RF) circuits to provide a capacitance that can be varied by changing the applied voltage. These types of diodes often are used for ...
Various configurations (Colpitts, Pierce, Clapp etc) are described in literature [Ref(1)]. Depending on the frequency requirements, various devices like MESFETs, pHEMTs, and HBTs can be used for VCO ...
