HMC472ALP4 / 472ALP4E v02.0420 0.5 dB LSB GaAs MMIC 6-BIT DIGITAL POSITIVE CONTROL ATTENUATOR, DC - 3.8 GHz Typical Applications Features The HMC472ALP4E is ideal for: 0.5 dB LSB Steps to 31.5 dB Single Control Line Per Bit 3G Infrastructure & access points TTL/CMOS Compatible Control Cellular/3G, LTE & UMB 0.25 dB Typical Step Error WiMAX, WiBN & Fixed Wireless Single +5V Supply Test Equipment and Sensors 24 Lead Ceramic 4x4mm SMT Package: 16mm GSM, WCDMA & TD-SCDMA Functional Diagram General Description The HMC472ALP4E are broadband 6-bit GaAs IC digital attenuators in low cost leadless surface mount packages. This single positive control line per bit digital attenuator incorporates off chip AC ground capacitors for near DC operation, making it suit- able for a wide variety of RF and IF applications. Covering DC to 3.8 GHz, the insertion loss is less than 2.0 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 0.25 dB typical step error with an IIP3 of +54 dBm. Six TTL/ CMOS control inputs are used to select each attenua- tion state. A single Vdd bias of +5V is required. Electrical Specifications, T = +25 C, With Vdd = +5V & Vctl = 0/+5V (Unless Otherwise Noted) A Parameter Frequency (GHz) Min. Typ. Max.
