HMC425LP3 / 425LP3E v03.0409 0.5 dB LSB GaAs MMIC 6-BIT DIGITAL POSITIVE CONTROL ATTENUATOR, 2.2 - 8.0 GHz ATTENUATORS - DIGITAL - SMT 5 Typical Applications Features The HMC425LP3 / HMC425LP3E is ideal for: 0.5 dB LSB Steps to 31.5 dB • WLAN & Point-to-Multi-Point Single Control Line Per Bit • Fiber Optics & Broadband Telecom ± 0.5 dB Typical Bit Error • Microwave Radio & VSAT Single +5V Supply • Military 3x3 mm SMT Package Functional Diagram General Description The HMC425LP3 & HMC425LP3E are broadband 6-bit GaAs IC digital attenuators in low cost leadless surface mount packages. Covering 2.2 to 8.0 GHz, the insertion loss is less then 3.8 dB typical. The attenuator bit values are 0.5 (LSB), 1, 2, 4, 8, and 16 dB for a total attenuation of 31.5 dB. Attenuation accuracy is excellent at ± 0.5 dB typical step error with an IIP3 of +40 dBm. Six control voltage inputs, toggled between 0 and +3 to +5V, are used to select each attenuation state. A single Vdd bias of +3 to +5V is required. Electrical Specifi cations, TA = +25° C, With Vdd = +5V & Vctl = 0/+5V (Unless Otherwise Noted) Frequency (GHz) Parameter Typ. Max.
