SMI 70-S(XX)
450 MHz Ceramic Microplexer
DESCRIPTION
Extremely small and lightweight ceramic duplexer (Extremely small: only
8 cm 3 !).
Ideal for integration in portable 450 MHz cellular radio telephones.
Low insertion loss by use of high-performance ceramic materials and
computer optimized interconnection networks.
Rugged mechanical design and low temperature drift.
High power handling – handles 30 W at 85° C when mounted on a
25 cm 2 heatsink!
Designed for direct drop-in on microstrip PCB.
Coplanar terminals save space and provide ease-of-manufacturing and a
non-discontinuity interface to the PCB.
Environment proof.
