Claims

1. A communications apparatus, comprising:

a switch circuit that alternates positions based on a switch control input to alternate the phase of a signal; and

a signal output circuit that outputs the signal having the alternating phase in response to the switch circuit, the outputted signal resonates in a first set of circuits but causes destructive interference in a different set of circuits.

2. The apparatus of claim 1, wherein a timing for the alternating position of the switch circuit causes a 180 degree phase shift between an incoming signal and the output signal.

3. The apparatus of claim 1, wherein a timing for the alternating position of the switch circuit results in a lowering of the average power of the output signal.

4. The apparatus of claim 1, wherein a timing for the alternating position of the switch circuit results in an increase the average power of the output signal.

5. The apparatus of claim 1 further comprising one of a bandpass filter and a resonant circuit and wherein a timing of the alternating position of the switch circuit outputs a same phase signal to one of a bandpass filter and a resonant circuit.

6. The apparatus of claim 1, wherein a timing of the alternating position of the switch circuit allows the output circuit to achieve resonance and pass a strong signal at a desired frequency and phase.

7. The apparatus of claim 1, wherein a timing of the alternating position of the switch circuit causes destructive interference in the output signal from one of an undesirable frequency and an undesirable phase of the output signal.

8. A method for communicating, comprising:

alternating positions of a switch circuit in response to a switch control input to alternate a phase of a signal; and

outputting the signal having the alternating phase in response to the switch circuit, the outputted signal resonates in a first set of circuits but causes destructive interference in a different set of circuits.

9. The method of claim 8, wherein alternating positions of the switch circuit further comprises causing a 180 degree phase shift between an incoming signal and the output signal.

10. The method of claim 8, wherein alternating positions of the switch circuit further comprises lowering an average power of the output signal.

11. The method of claim 8, wherein alternating positions of the switch circuit further comprises increasing the average power of the output signal.

12. The method of claim 8 further comprising outputting a same phase signal to one of a bandpass filter and a resonant circuit based on the alternating positions of the switch circuit.

13. The method of claim 8, wherein alternating positions of the switch circuit further comprises allowing an output circuit to achieve resonance and pass a strong signal at a desired frequency and phase.

14. The method of claim 8, wherein alternating positions of the switch circuit further comprises causing destructive interference in the output signal from one of an undesirable frequency and an undesirable phase of the output signal.
