Chip RF Attenuator Slide 4

There are two types of attenuator circuits: variable and fixed. Walsin utilizes fixed type attenuator designs, which are the most popular in the wireless industry. Fixed type attenuators are available in either Pi or T schematics. Because of the symmetrical structure to the I/O ports, Pi network products have better electrical specifications which allows for a more convenient layout.
