Ceramic Discriminators for Communication

JTM

Ceramic communication JTM discriminator is consists of wide band piezoelectric resonator.
JTM Ceramic Discriminators for Communication
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. It is ideal for mobile communication equipment due to its small size and light weight.

Discriminator JTM including features with small in size and lightweight, 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 and storage temperature range:-40°C to +85°C.
