| v00.0403 MICROWAVE CORPORATION HMC467LP3 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 3 mm x 3 mm x 1 mm SMT Package 2 dB LSB GaAs MMIC 2-BIT DIGITAL POSITIVE CONTROL ATTENUATOR, DC - 6.0 GHz Typical Applications The HMC467LP3 is ideal for: 9 ATTENUATORS - SMT * Cellular; UMTS/3G Infrastructure * Fixed Wireless & WLL * Microwave Radio & VSAT * Test Equipment Functional Diagram General Description The HMC467LP3 is a broadband 2-bit GaAs IC digital attenuator in a low cost leadless surface mount package. 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.
