SAW filter technology in support of mobile communications at ESA
Abstract
Severe RF spectrum limitations imposed by international regulations make filtering, and principally channel filtering, a key parameter of mobile satellite service. This paper uses two examples to illustrate how these filtering requirements can be best fulfilled with surface acoustic wave (SAW) technology. Both fixed-bandwidth SAW filters and variable-bandwidth SAW filters are considered.
