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 .
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
