<p>Diode network configurations are disclosed in which cathode bias voltage is held substantially constant to provide an attenuator circuit in which return loss is optimized throughout a broad dynamic attenuation range. Preferred embodiments include PIN diodes arranged in a π having two attenuation control signals provided thereto. Alternative embodiments include PIN diodes arranged in a T network having two attenuation control signals provided thereto.</p> |
