Abstract:
1. A PIN diode network, comprising: an input port; an output port; a PIN diode configured to selectively couple the input port to the output port by application of a forward bias to the PIN diode, the PIN diode having a stray capacitance in an off state upon removal of the forward bias; a series circuit having a first inductor and a second inductor connected in series, the series circuit connected in parallel with the PIN diode, the first inductor configured to self-resonate at a first operating frequency of the PIN diode network with the stray capacitance of the PIN diode when the PIN diode is in the off state, the self resonance at the first operating frequency obtained by only the first inductor with the stray capacitance of the PIN diode; the second inductor configured to self-resonate at a second operating frequency of the PIN diode network with the stray capacitance of the PIN diode when the PIN diode is in the off state, the self resonance at the second operating frequency obtained by only the second inductor with the stray capacitance of the PIN diode.
