RFMW Ltd. announces design and sales support for a 75 ohm digital step attenuator (DSA). The Qorvo QPC3614 offers 6-bits of attenuation with 0.5 dB LSB step size providing 31.5 dB of attenuation range from 5 to 1500 MHz. 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 >65 dBm), fast switching speed of <500 nS and low insertion loss of 1.4 dB typify performance. SOI technology improves robustness and allows on-board logic control for serial interface. Qorvo offers this DSA in a 3 x 3 mm QFN package.
