Designed to control the frequency of crystal oscillator circuits, the 3022 series of high-ratio, hyperabrupt varactor tuning diodes is designed to deliver a dc bias control voltage from -0.3V to -4V.
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 ...
A recent project evaluated the feasibility of a dynamic load modulation (DLM) RF power amplifier for 5G. DLM amplifiers typically use high-voltage varactor diodes in their output network, which need ...
