HMC467LP3 / 467LP3E v01.0705 2 dB LSB GaAs MMIC 2-BIT DIGITAL POSITIVE CONTROL ATTENUATOR, DC - 6 GHz 5 ATTENUATORS - SMT Typical Applications The HMC467LP3 / HMC467LP3E is ideal for: • Cellular; UMTS/3G Infrastructure • Fixed Wireless & WLL • Microwave Radio & VSAT • Test Equipment Features 2 dB LSB Steps to 6 dB High IP3: +50 dBm ± 0.2 dB Typical Bit Error Single Control Line Per Bit Single +5V Supply 3x3 mm SMT Package Functional Diagram General Description The HMC467LP3 & HMC467LP3E are broadband 2-bit GaAs IC digital attenuators in low cost leadless surface mount packages. Covering DC to 6.0 GHz, the insertion loss is less than 0.7 dB typical. The attenuator bit values are 2 (LSB) and 4 dB for a total attenuation of 6 dB. Attenuation accuracy is excellent at ± 0.2 dB typical step error with an IIP3 of +50 dBm. Two control voltage inputs, toggled between 0 and +5V, are used to select each attenuation state. A single Vdd bias of +5V is required. Electrical Specifi cations, TA = +25° C, With Vdd = +5V & Vctl = 0/+5V* Parameter Insertion Loss Attenuation Range Return Loss (RF1 & RF2, All Atten.
