Patent ID: 8249129

Claim:
A wideband frequency hopping spread spectrum transmitter, comprising: sampling circuitry configured to receive a transmit signal at an intermediate frequency (f IF ) and to receive sampling signals at a sample clock frequency (f S ) and configured to generate sampled output signals having a plurality of frequency components, the frequency components including frequencies at two or more harmonics of f S plus and minus f IF ; frequency select filter circuitry configured to receive the sampled output signals and to receive a frequency selection signal, the frequency select filter circuitry configured to provide a plurality of different selectable filter passband frequency ranges across a bandwidth that includes at least two harmonics of the sample clock frequency (f S ), the frequency select filter circuitry further having an output signal within a selected filter passband frequency range that includes one frequency component of the sampled output signals; and frequency hopping control circuitry configured to output the frequency selection signal and to adjust the frequency selection signal over time so that the output signal hops to different frequency components depending upon the selected filter passband frequency range.
