Low pass T-section digital phase shifter apparatus |
摘要 |
A low pass T-section digital phase shifter apparatus having a pair of serially connected inductor-diode combinations connected in series which includes a parallel circuit connected between the common junction and ground. The parallel circuit has an inductor in parallel with a series capacitor and diode to provide a balanced insertion loss at each diode switching state. When the diodes are in the forward-biased state they act as closed short circuit switches. When the diodes are reversed-biased, the inductance in the series circuit resonates with the diode capacitance to provide a short path to the RF signal to pass the center frequency of the RF signal at the desired phase.
