Programmable power regulator for medium to high power RF amplifiers with variable frequency applications

摘要

A power regulator regulates the power provided to a transistor-based circuit, such as that which might be employed in a high stability MTI radar system. According to the invention, a variable reference voltage is controlled based on the frequency of operation. The output voltage of the power regulator is then modified accordingly. Preferably, the reference voltage is controlled based on the location of the target frequency in relation to the overall operational frequency band, which has been divided into a series of sub-bands.
