HMC425LP3

ATTENUATORS - DIGITAL - SMT HMC425LP3 / 425LP3E v03.0409 0.5 dB LSB GaAs MMIC 6-BIT DIGITAL POSITIVE CONTROL ATTENUATOR, 2.2 - 8.0 GHz 5 Typical Applications The HMC425LP3 / HMC425LP3E is ideal for: WLAN & Point-to-Multi-Point Fiber Optics & Broadband Telecom Microwave Radio & VSAT Military Features 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 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. 5 - 116 Electrical Specifications, TA = +25° C, With Vdd = +5V & Vctl = 0/+5V (Unless Otherwise Noted) Parameter Insertion Loss Attenuation Range Frequency Min.
