The Pi network design and compact chip size of the WA04P series makes it suitable to be used in wireless communication applications including: mobile phones, tablets and laptops. The WA04P series supports 0 ~ 20 dB attenuation between DC to 3 GHz. To select an attenuator the electrical specifications a designer needs to consider are the attenuation, VSWR, characteristic impedance, rated power and limited voltage. In radio frequency applications the characteristic impedance is 50 ohms and VSWR is less than 2 in most cases.
