Abstract
Systems and methods for controlling phase or delay in multi-channel radio frequency applications. The system includes a local oscillator, a frequency generator, a clock buffer, a plurality of mixers and a plurality of filters. The frequency generator generates an intermediate frequency output signal which can be received by the clock buffer. The clock buffer creates multiple phase-adjusted reference frequency signals that are each different in phase. A local oscillator generates a plurality of local oscillator signals having the same frequency and phase. A plurality of mixers produce a plurality of RF signals based at least in part on the plurality of local oscillator signals and the plurality of phase-shifted reference frequency signals.
