The DLL-048R-2.14G, a member of the Multi-Mix

®

DLL family of delay lines, provides a mean delay of

4.85 nS in the UMTS band and features low insertion loss and low VSWR. The DLL-048R-2.14G exhibits

excellent phase linearity and amplitude flatness over the 2110 - 2170 MHz frequency range. The Multi-

Mix DLL-048R-2.14G is intended for use in power amplifier linearization networks such as feedforward

and predistortion.

DLL delay lines are fusion bonded multilayer stripline structures. The DLL series offers an excellent alter-

native to expensive coaxial and delay filter structures. The fusion bonding process yields a homgeneous

monolithic dielectric structure with reliability, ruggedness and electrical and thermal performance that is

superior to conventional adhesive bonding techniques.
