HMC472ALP4E General Description

Incorporating off-chip AC ground capacitors for DC operation, the HMC472ALP4E offers low insertion loss of less than 2.0 dB typical. This ensures minimal impact on signal quality, making it ideal for applications where signal integrity is crucial. The attenuator is controlled via six TTL/CMOS inputs, allowing for easy selection of attenuation states. Additionally, the device operates on a single Vdd bias of +5V, simplifying power requirements
