Ⅶ.Working principle of ADMV4420ACPZ

1.Control voltage function: In ADMV4420ACPZ, the path of the RF signal is controlled by controlling the reverse bias voltage of the PIN diode. When an appropriate control voltage is applied, the on-resistance of the PIN diode changes, thereby changing the transmission path of the RF signal.

A PIN diode is a special diode whose structure includes a P-type region, an Intrinsic (I) region and an N-type region. The I region is a carrier-free semiconductor material with high resistance. When a reverse bias voltage is applied, the resistance of the I region increases, thereby reducing the conduction current of the diode.

3.Radio frequency signal transmission: Under normal working conditions, radio frequency signals can be transmitted between different channels of ADMV4420ACPZ to realize signal selection and switching. When the control voltage changes, the transmission path of the radio frequency signal will change accordingly, thereby realizing the function of the radio frequency switch.

By controlling each PIN diode of ADMV4420ACPZ, the switching and selection of RF signals can be realized, thereby realizing the connection or switching between different signal sources.
