There are other benefits to using a DAC to bias a varactor diode. For example, multiple-output-channel DAC devices can be used in a multistage application. Additionally, in a four-channel DAC ...

The SMV1430-040LF miniature 0402 abrupt varactor diode is ideal for VCO, phase noise, frequency control and voltage tuned filter applications requiring low resistance and large capacitance over a ...

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 ...

In the shunt connection, the large RF signal voltage modulates the unbiased PIN diode's junction capacitance due to the varactor effect and this generates significantly more distortion. As a result, ...
