• LOW COST
TECHNICAL DESCRIPTION
MULTI-MIX^® DELAY LINES
APPLICATIONS
• GSM
• BASE STATION POWER AMPLIFIER
LINEARIZATION NETWORKS
• FEED FORWARD
• PRE-DISTORTION
• ADAPTIVE INTERFERENCE CANCELLATION
The DLL-057R-0.94G, a member of the Multi-Mix^® DLL family of delay lines, provides a mean delay of
5.68 nS in the GSM band and features low insertion loss and low VSWR. The DLL-057R-0.94G exhibits
excellent phase linearity and amplitude flatness over the 925 - 960 MHz frequency range. The Multi-Mix^®
DLL-057R-0.94G 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.
