The HMC1095LP4E is a broadband 6-bit GaAs IC Digital Attenuator that operates from DC to 3 GHz. This attenuator incorporates off-chip AC ground capacitors for near DC operation, making it suitable for a wide variety of RF and IF applications. The dual mode control interface is CMOS/TTL compatible, and accepts either a three wire serial input or a 6 bit parallel word. The HMC1095LP4E also features a user selectable power up state and a serial output port for cascading other Hittite serial controlled components. It is packaged in a 4x4 mm QFN leadless package with internal matching to 75 Ohms.
