HMC1019ALP4E

HMC1019ALP4E is a broadband 5bit GaAs IC digital attenuator in a low cost leadless surface mount package. Attenuation accuracy is excellent at ±0.3 dB typical step error with an IIP3 of +45dBm. The control interface is CMOS/TTL compatible and accepts a three wire serial input. This features a user selectable power up state and a serial output port for cascading other Analog Devices serial controlled components. Typical application includes fibre optics & broadband telecom, microwave radio & VSAT, military radios, radar & ECM, space applications, sensors, test and measurement equipment.
