HMC541LP3 Overview
The HMC541LP3 & HMC541LP3E are broadband 1-bit GaAs IC digital attenuators in low cost leadless surface mount packages. This single positive control line digital attenuator utilizes off chip AC ground capacitors for near DC operation, making it suitable for a wide variety of RF and IF applications. Covering DC to 5 GHz, the insertion loss is less than 1 dB typical.
