The QPC3624 from Qorvo is a 75 ohm, 6-bit digital step attenuator that operates from 47 to 2000 MHz. It has an attenuation range of up to 31.5 dB with 0.5 dB steps and a low insertion loss of 1.3 dB at 1 GHz. The attenuator has three modes of control: serial, latched parallel, and direct parallel programming. Its patented circuit architecture provides overshoot-free transient switching performance. The QPC3624 is available in a 24-pad 4 x 4 x 0.85 mm QFN package and is ideal for optical nodes, MDU amplifiers, pre-amplifier attenuation and return attenuation applications.
