  • PIN diode modulator
    Patent number: 4581637
    Abstract: A sine wave modulator for decoding a sine wave encoded television signal includes a passive attenuation network comprising a pi-arrangement of PIN diodes. The encoded signal is supplied to the input port and the decoded signal is taken from the output port. A common bias arrangement for the series-shunt-connected PIN diodes results in the impedance of one PIN diode changing oppositely to the impedance of the other PIN diodes such that the impedance presented to the input and output ports remains substantially constant.
