Patent ID: 7379515

Claim:
A method of steering an antenna beam and frequency translating an electromagnetic (EM) signal that corresponds to said antenna beam, the method comprising the steps of: (1) receiving a first EM signal and a second EM signal; (2) generating a local oscillator (LO) signal; (3) generating a first control signal based on said local oscillator signal, comprising the steps of (a) level shifting said local oscillator signal by a first voltage resulting in a first biased LO signal, and (b) triggering a first pulse generator based on said first biased LO signal, to generate said first control signal; (4) sampling said first EM signal according to said first control signal to generate a first down-converted signal, and sampling said second EM signal according to a second control signal to generate a second down-converted signal, wherein said second control is phase shifted with respect to said first control signal and thereby said second down-converted signal is phase-shifted with respect to said first down-converted signal.
