FILTERS
FOR COMMUNICATIONS EQUIPMENT–DISCRIMINATORS
CDB/CDBC/CDBM455kHz
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.
Available in 450kHz and
455kHz versions.
FEATURES
s Small in size and light weight
s Realize non-adjustment in
detection circuit
s High sensitivity and stability
s Wide range of standard products are
available for various ICs
s Operating temperature range:
–20°C to +80°C
Storage temperature range:
–40°C to +85°C
