HMC467LP3 / 467LP3E v01.0705 2 dB LSB GaAs MMIC 2-BIT DIGITAL POSITIVE CONTROL ATTENUATOR, DC - 6 GHz ATTENUATORS - SMT 5 Typical Applications Features The HMC467LP3 / HMC467LP3E is ideal for: 2 dB LSB Steps to 6 dB * Cellular; UMTS/3G Infrastructure High IP3: +50 dBm * Fixed Wireless & WLL 0.2 dB Typical Bit Error * Microwave Radio & VSAT Single Control Line Per Bit Single +5V Supply TE * Test Equipment 3x3 mm SMT Package General Description Functional Diagram B SO LE The HMC467LP3 & HMC467LP3E are broadband 2-bit GaAs IC digital attenuators in low cost leadless surface mount packages. Covering DC to 6.0 GHz, the insertion loss is less than 0.7 dB typical. The attenuator bit values are 2 (LSB) and 4 dB for a total attenuation of 6 dB. Attenuation accuracy is excellent at 0.2 dB typical step error with an IIP3 of +50 dBm. Two control voltage inputs, toggled between 0 and +5V, are used to select each attenuation state. A single Vdd bias of +5V is required.
