Multi-mode, multi-band communication system

A method of communicating, comprising the steps of:

• (1) selecting an information signal from one or more information signals as a selected information signal;
• (2) determining a desired frequency for an oscillating signal;
• (3) combining said selected information signal with a bias signal to create a bias/reference signal;
• (4) gating said bias/reference signal at a rate that is a function of said oscillating signal to create an amplitude modulated harmonically rich signal;
• (5) enabling a filter circuit to process said amplitude modulated harmonically rich signal;
• and
• (6) filtering, in said filter circuit, said amplitude modulated harmonically rich signal to isolate one or more desired harmonics, each of said one or more desired harmonics being a desired output signal having a desired output frequency,
• wherein said gating step is performed by a frequency translation module having a square wave generator that accepts said modulated oscillating signal and generates a square wave, a pulse shaper that accepts said square wave and generates a string of pulses, and a switch being controlled by said string of pulses and being connected to said bias signal and generating said harmonically rich signal, said switch having a first port, a second port, and a control port, wherein said string of pulses is connected to said control port, said bias signal is connected to said first port, said harmonically rich signal is connected to said first port, and a ground is connected to said second port.

A system for communicating, comprising:

• an information signal conditioning module to accept one or more information signals and to output one or more conditioned information signals,
• a signal selection module to accept said one or more conditioned information signals and to output a selected information signal,
• a modulation and frequency selection module to accept said selected information signal and to output an oscillating signal,
• a frequency translation module to accept said oscillating signal and a bias/reference signal, and to output a harmonically rich signal, and
• a frequency band selection module to accept said harmonically rich signal and to output one or more desired output signals,
• wherein said frequency translation module comprises a square wave generator that accepts said oscillating signal and generates a square wave, a pulse shaper that accepts said square wave and generates a string of pulses, and a switch being controlled by said string of pulses and being connected to said bias/reference signal and generating said harmonically rich signal, and
• wherein said switch has a first port, a second port, and a control port, wherein said string of pulses is connected to said control port, said bias/reference signal is connected to said first port, and said harmonically rich signal is connected to said second port.
