Extremely small and lightweight ceramic duplexer (Extremely small: only 12 cm³ !). Ideal for integration in portable 450 MHz cellular sevices.
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 watts at 85 °C when mounted on a 40 cm 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.
Rejection of image frequency of receiver.
Environment proof.
