PIEZO FILTERS
HIGH PERFORMANCE CERAMIC DISCRIMINATORS
FOR MOBILE COMMUNICATION EQUIPMENT CDB/CDBC/CDBM 455kHz
Ceramic discriminator consists of wide band piezoelectric
resonator. It is ideal for mobile communication equipment
due to its small size and light weight. Standard line includes
products for a wide range of applications, from cordless
telephones to cellular telephones, making non-adjustment
and shrinking of the detection circuit possible.
FEATURES
ꢀ Small in size and light weight
ꢀ Realize non-adjustment in detection circuit
ꢀ High sensitivity and stability
ꢀ Wide range of standard products are available for various ICs
ꢀ Operating temperature range: –20°C to +80°C
Storage temperature range: –40°C to +85°C
