DIRECT CONVERSION RECEIVER EMPLOYING SUBHARMONIC FREQUENCY TRANSLATOR ARCHITECTURE AND RELATED PREPROCESSOR |
摘要 |
A direct conversion receiver for receiving a first input signal and directly downconverting it to baseband frequencies. The receiver includes a frequency translator which is responsive to a phase-split input signal having 2n components, wherein n is an integer greater than 1. The phase-split signal has a period T which is about n times the period of the first input. The frequency translator alternates, at a rate of about 2n/T, between switching the first input signal to a first output, and switching the first signal to a second output. A preprocessor is available to improve the switching characteristics of the phase-split input signal.
