■ Description
Miniature high selectivityYIG-tuned bandpass filters have a broad frequency coverage, low volume and low
energy-consuming. The devices have a width of about 1 inch, a height below 20mm, a low insert loss and a
extremely high selectivity, meeting the miniaturizing requirements of the new generation systems. All the
miniature YIG-tuned filters can be offered both indenpendently and combining with special analor or digital
drivers.
