Introduction

6-Bit Digital Step Attenuator, 1MHz to 4000M Digital step attenuators are used in receivers and transmitters to provide gain control. The F1912 is a 6-bit step attenuator optimized for these demanding applications. The silicon design has very low insertion loss and low distortion (greater than +60 dBm IIP3). The device has pinpoint accuracy. Most importantly, the F1912 includes Glitch-FreeTM technology, which results in low overshoot and ringing during MSB transitions. Glitch-FreeTM technology so PA or ADC will not be damaged during when transitions. Extremely accurate with low distortion. Lowest insertion loss for best SNR
