WA04P Datasheet, PDF (2/6 Pages) List of Unclassifed Manufacturers – Unbalanced p type attenuator circuit in one chip (1.0mm x 1.0mm)

Approval sheet
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.
