The HMC624LP4 is a broadband 6-bit digital attenuator IC that operates from DC to 6 GHz. It has an attenuation range of 31.5 dB with a 0.5 dB LSB and an insertion loss of under 2.2 dB through the band. The attenuator can handle an input IP3 of up to 55 dBm and has a switching speed of 150 ns. It requires a 5 V supply (Vdd) and is available in a 4x4 mm QFN leadless package, and requires no external matching components. This digital attenuator incorporates off-chip AC ground capacitors for near DC operation, making it suitable for a wide variety of RF and IF applications.
