Abstract
A system and method for designing a broadband tuner such that VCO pulling is minimized and gaps in frequency coverage are avoided, while total power consumption is reduced, is disclosed. A broadband spectrum is divided into sub-bands and various multipliers to a local oscillator output are introduced. In this fashion, the present invention allows a local oscillator within the broadband tuner to always generate signals that lie outside of the broadband spectrum for a particular broadband application. Additionally, a modulus ratio for a dual modulus prescaler with the local oscillator is maximized, thereby reducing power consumption.
