單獨諧振(共振)電路通常聯接在一起比只有一個單一諧振器在某些頻率上可以產生更多的衰減.

It uses "than", because in the sentence it has "more attenuation". It is similar to:

My wife makes more money than I (do).

He has more opportunity than ever.

This "attenuation" can apply to many different fields: light, earthquake, electromagnetic, radio … Since it doesn't indicate the application, so I can just use "衰減" as a general term to translate.

Even though it mentioned "circuit," but it can still be in different fields. All it says is to indicate the source, not the application.

There are many different types of attenuation:

sunlight is attenuated by dark glasses,

X-rays are attenuated by lead, or

light and sound are attenuated by water

For someone whose Chinese isn't fluent, you sure commit a lot of Chinglish errors.

"Even though" and "but" in the same sentence. ("Because" and "so")
