Ceramic Discriminators for Communications Equipment

kHz Type Ceramic Discriminators

Ceramic discriminator consists of a wide band

piezoelectric resonator.

It is ideal for mobile communications equipment due to

its small size and light weight.

Standard line includes products for a wide range of

applications, from cordless telecom to cellular

telephone. Practically adjustment free at the detection

circuit, small size is suitable for downsizing.

c Features

1. Small in size and light weight

2. Adjustment free at detection circuit

3. High sensitivity and stability

4. Wide range of standard products are available for

various ICs.

5. Operating temperature range: -20 to +80 (°C)

Storage temperature range: -40 to +85 (°C)
