If you don't mind a little home brewing, dig up the Jan 91 issue of RF Design magazine. The comb generator design by Ken Wyatt and Dick Cheney of HP can be built for about $50 and out performs the Royce source significantly! It is usable past 1 GHz and has much better "flatness" peak to peak. The RefRad may be a decent product, but you can do better than the Royce source for a whole lot less money. ------------------------------ Brent DeWitt U.S. EMC Technical Coordinator TUV Product Service, Inc.
