MULTI-BAND LO SELECTABLE WIDEBAND LNB USING PLL

摘要

The present invention relates to a low noise frequency converter capable of oscillating various frequencies according to the user's selection. The user selects at least one or more frequencies from among a plurality of frequencies. The low noise frequency converter receives a control signal from the user, and oscillates a frequency selected by the user according to the received control signal. The low noise frequency converter uses the oscillated frequencies for frequency conversion.

主权项

1. A low noise frequency converter comprising:
a control signal receiver to receive a control signal determined based on a region in which the low noise frequency converter operates; a frequency determiner to determine a frequency of a local signal in response to the control signal; and a wideband phase-locked loop (PLL) local signal generator to generate the local signal corresponding to the determined frequency.
