Abstract
An apparatus includes a first circuit and a second circuit. The first circuit may be configured to inject charge into an I-region of a PIN diode in response to a first state of a control signal. The second circuit may be configured to remove charge from the I-region of the PIN diode in response to a second state of the control signal. A radio frequency switching time of the apparatus is generally about two orders of magnitude lower than a carrier lifetime of the PIN diode.
Claims20
An apparatus comprising:
- a first circuit configured to inject charge into an I-region of a PIN diode in response to a first state of a control signal;
- and
- a second circuit configured to remove charge from said I-region of said PIN diode in response to a second state of said control signal, wherein said first circuit and said second circuit reduce a switching time of said PIN diode.
A method of switching radio frequencies using a PIN diode, said method comprising:
- injecting charge into an I-region of said PIN diode in response to a control signal having a first state;
- and
- removing charge from said I-region of said PIN diode in response to said control signal having a second state, wherein said injecting and said removing reduce a switching time of said PIN diode.
