Claim:
A wideband frequency hopping spread spectrum transceiver, comprising: a wideband frequency hopping spread spectrum transmitter, comprising: sampling circuitry configured to receive a transmit signal at a transmit intermediate frequency f IFTX and to receive sampling signals at a transmit sample clock frequency f STX 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 STX plus and minus f IFTX ; 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 transmit sample clock frequency f STX , 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; 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; and transmit antenna circuitry configured to transmit the output signal as it hops to different frequency components over time; and a wideband frequency hopping spread spectrum receiver, comprising: receive antenna circuitry configured to receive input receive signals from a wideband frequency hopping spread spectrum transmitter as it hops to different frequency components over time; sampling circuitry configured to receive the input receive signals at a radio frequency f RF , to receive sampling signals at a receive sample clock frequency f SRX and to generate sampled output signals having a plurality of frequency components, the frequency components including frequencies at two or more harmonics of f SRX plus and minus f RF , and the frequency components including at least one frequency component at a receive intermediate frequency f IFRX ; and filter circuitry configured to provide a filter passband frequency range including the receive intermediate frequency f IFRX , the filter circuitry further configured to receive the sampled output signals and to have an output signal that includes the frequency component of the sampled output signals at the receive intermediate frequency f IFRX .
