WA04P Series Attenuators

Walsin Technology Corporation's WA04P series chip attenuators for wireless devices

Image of Walsin's WA04P Series Walsin's WA04P series chip attenuators are designed to satisfy most radio frequency applications for wireless devices, such as mobile phones, tablets, and laptops. With attenuation values ranging from 0 dB to 20 dB and frequency ranges from DC to 3 GHz, miniaturized in size (1.0 mm x 1.0 mm), and highly reliable, the WA04P series may be applied to high speed and frequency circuits, i.e. GSM 2G / 3G / 4G LTE. The WA04P has characteristic impedance of 50 Ω and maximum working frequencies up to 3 GHz.

Having adopted π type attenuator circuit design, the Walsin chip attenuator is more convenient to layout with better electrical specification because of the symmetrical structure to the I/O port.
