HMC941LP4 / 941LP4E v00.0910 Attenuators - SMT 0.5 dB LSB GaAs MMIC 5-BIT DIGITAL ATTENUATOR, 0.1 - 33 GHz Typical Applications Features The HMC941LP4 / HMC941LP4E is ideal for: 0.5 dB LSB Steps to 15.5 dB • Fiber Optics & Broadband Telecom Single Positive Control Line Per Bit • Microwave Radio & VSAT ±0.5 dB Typical Bit Error • Military Radios, Radar & ECM High Input IP3: +45 dBm • Space Applications 16mm2 Leadless SMT Plastic Package • Sensors • Test & Measurement Equipment Functional Diagram General Description The HMC941LP4 & HMC941LP4E are broadband 5-bit GaAs IC digital attenuators in low cost leadless surface mount packages. Covering 0.1 to 33.0 GHz, the insertion loss is less than 4 dB typical. The attenuator bit values are 0.5 (LSB), 1, 2, 4, 8, for a total attenuation of 15.5 dB. Attenuation accuracy is excellent at ±0.3 dB typical step error with an IIP3 of +45 dBm. Five control voltage inputs, toggled between +5V and 0V, are used to select each attenuation state.
