Anaren introduces a line of RF Power-brand resistive components specially matched to Xinger®-brand circulators. The resistors are available in both flanged and surface mount configurations. Advantages of the devices include: quick, performance-optimizing approach to achieving isolator functionality with the SM circulator; uses the latest thick-film AlN ceramic design; and rugged, reliable, high-power handling. Operating temperature for the surface mount and flanged version is 55 to +150°C. VSWR for both versions is 1:25:1. Frequency for the surface mount part is DC - 3 GHz and DC - 5 GHz for the flanged part. Power handling is 25/50 watts for the surface mount part, with 50 watts possible when mounted to PCB with an excellent thermal contact to heat sink. The flanged part has a power handling of 100 watts.
