Approval sheet WA04P type chip attenuator 50, 0dB, 0.5dB to 20dB Size 1.0 x 1.0 mm Page 1 of 6 ASC WA04P V14 Feb. 2012 Approval sheet FEATURE 1. Unbalanced 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. Fig 1.
