Abstract

A single integrated chip has first and second voltage controlled oscillators and first and second buffers. The first voltage controlled oscillator has a first output defined by a first frequency band, and the second voltage controlled oscillator has a second output defined by a second frequency band. The first and second buffers selectively couple the first and second outputs to a common output. The first buffer is coupled between the first frequency controlled oscillator and the common output, and the second buffer is coupled between the second frequency controlled oscillator and the common output. The first buffer has a high output impedance when the second buffer couples the second output to the common output, and the second buffer has a high output impedance when the first buffer couples the first output to the common output.
