HMC540SLP3E

HMC540SLP3E is a broadband 4bit silicon IC digital attenuator. This single positive control line per bit 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 0.1GHz to 8GHz, the insertion loss is less than 1dB typical. The attenuator bit values are 1 (LSB), 2, 4 and 8dB for a total attenuation of 15dB. Attenuation accuracy is excellent at ± 0.2dB typical step error. The attenuator also features a IIP3 of +56dBm. Four TTL/CMOS control inputs are used to select each attenuation state. It is widely used in applications such as cellular infrastructure, wireless infrastructure, microwave radio & VSAT, test equipment and sensors etc.

• Low insertion loss is 1. 1dB maximum at (0.1GHz to 2GHz)
• Return loss is 22dB typical at (0GHz to 3.5GHz)
