FEATURE

1.

Unbalanced

π type attenuator circuit in one chip (1.0mm x 1.0mm)

2.

Mounting occupation area reduction

3.

Mounting assembly cost saving

APPLICATION

•

Attenuation, level control, impedance matching of high frequency signals of communication equipment;

•

Mobile phone (GSM, CDMA, PDC, etc,…)

•

Telecom

DESCRIPTION

The attenuator is constructed in a high grade ceramic body (aluminum oxide). Internal circuit is applied to the top

surface of the substrate, and its design determines the required attenuation value. The attenuation layer is

covered with a protective coating and a rectangular marker indicates input pin1 as shown in circuit configuration.
