HMC425LP3 425LP3E / v03.0409 0.5 dB LSB GaAs MMIC 6-BIT DIGITAL POSITIVE CONTROL ATTENUATOR, 2.2 - 8.0 GHz 5 Typical Applications Features The HMC425LP3 / HMC425LP3E is ideal for: 0.5 dB LSB Steps to 31.5 dB T M • WLAN & Point-to-Multi-Point Single Control Line Per Bit S • Fiber Optics & Broadband Telecom ± 0.5 dB Typical Bit Error - • Microwave Radio & VSAT Single +5V Supply L A • Military 3x3 mm SMT Package T I G DI Functional Diagram General Description - The HMC425LP3 & HMC425LP3E are broadband S 6-bit GaAs IC digital attenuators in low cost leadless R surface mount packages. Covering 2.2 to 8.0 GHz, O the insertion loss is less then 3.8 dB typical. The T attenuator bit values are 0.5 (LSB), 1, 2, 4, 8, and A 16 dB for a total attenuation of 31.5 dB. Attenuation U accuracy is excellent at ± 0.5 dB typical step error N with an IIP3 of +40 dBm. Six control voltage inputs, E toggled between 0 and +3 to +5V, are used to select T each attenuation state. A single Vdd bias of +3 to +5V T A is required.
