HMC424LP3

Attenuators - DIGITAL - SMT v08.0809 Typical Applications The HMC424LP3 / HMC424LP3E is ideal for: Basestation Infrastructure Fiber Optics & Broadband Telecom Microwave & VSAT Radios Military & Space Test Instrumentation Functional Diagram HMC424LP3 / 424LP3E 0.5dB LSB GaAs MMIC 6-BIT DIGITAL ATTENUATOR, DC - 13 GHz Features 0.5 dB LSB Steps to 31.5 dB Single Control Line Per Bit ± 0.5 dB Typical Bit Error 9mm2 Leadless SMT Plastic Package General Description The HMC424LP3 & HMC424LP3E are broadband 6-bit GaAs IC digital attenuators in low cost leadless surface mount packages. Covering DC to 13 GHz, the insertion loss is less then 4 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 +32 dBm. Six control voltage inputs, toggled between 0 and -5V, are used to select each attenuation state. A single Vee bias of -5V allows operation at frequencies down to DC. Electrical Specifications, TA = +25° C, With Vee = -5V & VCTL= 0/-5V Parameter Frequency (GHz) Min. Typ. Max.
