The advent of high-throughput satellite (HTS) systems has opened up new horizons for communication satellites. What we are seeing is a paradigm shift from conventional satellite systems (like fixed, broadcasting, and mobile satellite services) using singlebeam to multibeam HTS satellites capable of delivering very high throughput (>20 times the total throughput offered by typical fixed satellites) [1], [2]. The use of multiple-spot beams in HTS satellites has two advantages: 1) it results in better antenna gain (due to narrower beams) and thus an improved link budget, and 2) it improves spectral efficiency due to a high-frequency reuse factor. This increasing demand for higher throughput and more transponders is driving key technologies in satellite communications. The temperature-compensated filter is one such technology that offers substantial reduction in size and weight along with improved RF performance and power-handling capability compared to previous generations of output filters.
