PDD-2C-3.0G POWER DIVIDER PRELIMINARY REV: 003, 05/10/06 TECHNICAL DESCRIPTION FEATURES • 2000 - 4000 MHz • LOW LOSS • HIGH ISOLATION • EXCELLENT PHASE/AMPLITUDE BALANCE • SURFACE MOUNT • TAPE & REEL AVAILABLE APPLICATIONS • I&Q NETWORKS • POWER AMPLIFIERS • SIGNAL DISTRIBUTION The Multi-Mix® PDD series provides a 3 dB 0° in-phase power divider with low insertion loss, low VSWR, and high isolation. Accurate phase and amplitude balance make this series ideal for use in IQ networks, power amplifiers, radio transceivers, receiver multicouplers and RF signal distribution and processing equipment. PDD power dividers are fusion bonded multilayer stripline devices. The fusion bonding process yields a homogeneous monolithic dielectric structure with reliability, ruggedness, and electrical performance that is superior to conventional adhesive bonding techniques.
