HMC468ALP3E v01.0818 1dB LSB GaAs MMIC 3-BIT DIGITAL POSITIVE CONTROL ATTENUATOR, DC - 6GHz Typical Applications Features The HMC468ALP3E is ideal for: 1 dB LSB Steps to 7 dB High IP3: +55 dBm Cellular UMTS/3G Infrastructure 0.25 dB Typical Bit Error Fixed Wireless & WLL Single Control Line Per Bit Microwave Radio & VSAT Single +5V Supply Test Equipment 2 16 Lead 3x3 mm SMT Package: 9 mm General Description Functional Diagram The HMC468ALP3E is a broadband 3-bit GaAs IC digital attenuators in a low cost leadless sur- face mount package. Covering DC to 6.0 GHz, the insertion loss is less than 1 dB typical up to 4 GHz. The attenuator bit values are 1 (LSB), 2 and 4 dB for a total attenuation of 7 dB. Attenuation accu- racy is excellent at 0.4 dB typical step error with an IIP3 of +55 dBm. Three control voltage inputs, toggled between 0 and +5V, 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 A Parameter Frequency (GHz) Min. Typ. Max.
