Overview
The HMC1095LP4E is a broadband 6-bit GaAs IC Digital Attenuator produced by Analog Devices Inc. This component operates from DC to 3 GHz and is housed in a RoHS compliant 4x4 mm QFN leadless package. It incorporates off-chip AC ground capacitors for near DC operation, making it suitable for a wide variety of RF and IF applications. The attenuator features a dual mode control interface that is CMOS/TTL compatible, accepting either a three-wire serial input or a 6-bit parallel word. Additionally, it includes a user-selectable power-up state and a serial output port for cascading other serial-controlled components.
