3 / 4 page 1 1 0.5 dB LSB GaAs MMIC 6-BIT DIGITAL POSITIVE CONTROL ATTENUATOR, 2.2 - 8.0 GHz Functional Diagram Electrical Specifications, T A = +25° C, With Vdd = +5V & Vctl = 0/+5V (Unless Otherwise Noted) Typical Applications The HMC425 ALP3 / HMC425ALP3E is ideal for: • WLAN & Point-to-Multi-Point • Fiber Optics & Broadband Telecom • Microwave Radio & VSAT • Military 0.5 dB LSB Steps to 31.5 dB Single Control Line Per Bit ± 0.5 dB Typical Bit Error Single +5V Supply 3x3 mm SMT Package The HMC425 ALP3 & HMC425ALP3E are broad- band 6-bit GaAs IC digital attenuators in low cost leadless surface mount packages. Covering 2.2 to 8. 0 G H z , 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. Parameter Frequency (GHz) Min. Typ. Max.
