Attenuators - SMT v00.0910 Typical Applications The HMC941LP4 / HMC941LP4E is ideal for: Fiber Optics & Broadband Telecom Microwave Radio & VSAT Military Radios, Radar & ECM Space Applications Sensors Test & Measurement Equipment Functional Diagram HMC941LP4 / 941LP4E 0.5 dB LSB GaAs MMIC 5-BIT DIGITAL ATTENUATOR, 0.1 - 33 GHz Features 0.5 dB LSB Steps to 15.5 dB Single Positive Control Line Per Bit ±0.5 dB Typical Bit Error High Input IP3: +45 dBm 16mm2 Leadless SMT Plastic Package 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.
