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 ...

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, ...
