HMC1018LP4E v01.1211 1.0 dB LSB GaAs MMIC 5-BIT DIGITAL ATTENUATOR, 0.1 - 30 GHz Attenuators - Digital - SMT Typical Applications Features The HMC1018LP4E is ideal for: 1.0 dB LSB Steps to 31 dB Fiber Optics & Broadband Telecom TTL/CMOS Compatible, Serial Control Microwave Radio & VSAT Unique Asynchronous Mode Control Allows Military Radios, Radar & ECM Immediate Attenuation Level Setting Space Applications Sensors Test & Measurement Equipment OLETE Functional Diagram ±1.0 dB Typical Bit Error High Input IP3: +43 dBm 24 Lead 4x4mm SMT Package: 16mm2 General Description The HMC1018LP4E is a broadband 5-bit GaAs IC digital attenuator in a low cost leadless surface mount package. Covering 0.1 to 30.0 GHz, the insertion loss is less than 5.5 dB typical. The attenuator bit values are 1.0 (LSB), 2, 4, 8, 16 for a total attenuation of 31 dB. Attenuation accuracy is excellent at ±0.4 dB typical step error with an IIP3 of +43 dBm. The control interface is CMOS/TTL compatible and accepts a three wire serial input. The HMC1018LP4E features a user selectable power up state and a serialoutput port for cascading other Hittite serial controlled components.
