DLL-115R-1.96G DELAY LINE PRELIMINARY REV: 006, 12/02/04 TECHNICAL DESCRIPTION MULTI-MIX® DELAY LINES APPLICATIONS • PCS • BASE STATION POWER AMPLIFIER LINEARIZATION NETWORKS • FEED FORWARD • PRE-DISTORTION • ADAPTIVE INTERFERENCE CANCELLATION FEATURES • 1930 - 1990 MHz • LOW LOSS • LOW VSWR • SURFACE MOUNT • LOW COST The DLL-115R-1.96G, a member of the Multi-Mix® DLL family of delay lines, provides a mean delay of 11.45 nS in the PCS band and features low insertion loss and low VSWR. The DLL-115R-1.96G exhibits excellent phase linearity and amplitude flatness over the 1930 - 1990 MHz frequency range. The MultiMix® DLL-115R-1.96G 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 alternative 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.
