Abstract
A frequency manager in a multi-band wireless microphone system provides the synchronization of fixed RF devices (for example, transceivers) operating in distant parts (for example, two or more frequency bands) of the frequency spectrum. Each transceiver may be paired with a wireless microphone and provides synchronization with the paired wireless microphone. Antenna signals are separated or combined into a plurality of frequency bands using a multi-band filter. Band-specific low noise amplifiers and power amplifiers may be utilized for each frequency band so amplifier performance can be optimized. Prior to distribution by a splitter, the plurality of frequency bands is combined or separated using a second multi-band filter. Transceivers that are connected to the frequency manager may then independently operate in one band, different frequency bands or a combination of bands. A cascade feature allows multiple frequency managers to synchronize, further increasing the system's simultaneous microphone channel capacity.
