In addition to the voltage values for a given capacitance mentioned in the data sheet, measurements were taken for many more biasing voltage combinations for each varactor diode from 0 to 21V.
As a varactor diode we selected an Infineon BB833 in SOD323 package, designed to operate up to 2.5 GHz [31].
TD stands for tunnel diode, VD for varactor diode (Varicap), and HEMT for High-Electron Mobility Transistor.
The mismatch was finally traced to the resistance offered by the varactor diode. The resistance of the varactor varies with the applied voltage as well as the frequency of operation.
In this paper, the loaded HDGS/EDMS varactor diode is introduced to realize the tunable dual-stop-band filter.
The HMC588LC4B Wideband HBT MMIC VCO incorporates the resonator, negative resistance device and varactor diode. It provides an output tuning range of 8.0 GHz to 12.5 GHz, high output power of +5 dBm and low SSB Phase Noise of -93 dBc/Hz at 100 kHz offset.
The variable phase shifter uses a varactor diode 1T362 from Sony and a variable attenuator, a PIN diode HSMP-4810 from HP.
Summary: Global varactor diode market is expected to cross a value of US$ 800 Mn by 2027, expanding at a CAGR of more than 6.5% from 2019 to 2027.
The research study is titled " Global Varactor Diode Market - In-Depth Analysis with Booming Trends Supporting Growth and Forecast till 2027 " which encloses important data about the production, consumption, revenue and market share, merged with information related to the market scope and product overview.
The varactor-loaded dual-band design is simulated where each varactor diode is simply modeled as a variable capacitance C.
In these designs, the reactances [X.sub.m] and/or [X.sub.n] are implemented using a transmission line connected to a varactor diode. This is possible since the varactor diode is in essence a variable reactance.
Recently, the authors have proposed a novel tunable reflectarray element based on the use of an aperture-coupled patch electronically driven by a single varactor diode [710].
