Abstract
This paper presents recent advancements in RF filtering techniques through the use of acousto-optics and a special purpose array of wideband photodiodes. An electronically programmable filter may be synthesized by inserting this array of photodiodes into the frequency plane of an optical spectrum analyzer. A description of the optical system, the photodiode array and some experimental results are presented.
