Dielectric Resonators DR Series are widely used in voltage controlled oscillators
and filters for cellular phone, cordless phone and so on. Features
with high dielectric constant and high Q, excellent Solderability.
Token DR series designs are available from 800 MHz to 4800 MHz by
10 MHz standard and custom packages are available.
Please consult our sales representatives or engineers as regards the
products for other frequency.
