RFMW offers Qorvo’s Overshoot-Free 6-Bit Digital Attenuator for CATV

Qorvo 75 ohm QPC3614 offers 6-bits of attenuation with 0.5dB LSB step size providing 31.5dB of attenuation range from 5 to 1500MHz.RFMW, Ltd. announces design and sales support for a 75 ohm Digital Step Attenuator (DSA). The Qorvo QPC3614 offers 6-bits of attenuation with 0.5dB LSB step size providing 31.5dB of attenuation range from 5 to 1500MHz. Featuring overshoot-free transient switching between attenuation steps, the QPC3614 is ideal for 75 ohm applications such as optical nodes, point-to-point, MDU amplifiers, pre-amplifier attenuation, inter-stage attenuation, return attenuation, AGC and tilt control. High linearity (IIP3 >65dBm), fast switching speed of <500nS and low insertion loss of 1.2dB typify performance. The attenuator features three control modes: serial, latched parallel and direct parallel. Qorvo offers this DSA in a 4.2×4.2mm QFN package.
