HMC542BLP4E v00.1212 0.5 dB LSB GaAs MMIC 6-BIT DIGITAL SERIAL CONTROL ATTENUATOR, DC - 4 GHz Typical Applications Features t he HMC542Bl P4e is ideal for: 0.5 dB LSB Steps to 31.5 dB TTL/CMOS Compatible Serial Data Interface Cellular/PCS/3G Infrastructure t SPI Compatible Serial Output ISM, MMDS, WLAN, WiMAX, & WiBro 0.25 dB Typical Step Error Microwave Radio & VSAT Single +5V Supply Test Equipment and Sensors 24 Lead 4x4 mm QFN Package: 16 mm Functional Diagram General Description t The HMC542BLP4E is a broadband 6-bit GaAs IC g digital attenuator with a CMOS compatible serial to parallel driver in low cost leadless surface mount package. This serial control digital attenuator incorp rates off chip AC ground capacitors for near DC opera- tion, making it suitable for a wide variety of RF and t IF applications. Covering DC to 4 GHz, the inser- tion loss is 1.7 dB and the attenuator bit values are 0.5 (LSB), 1, 2, 4, 8, and 16 dB for a total attenua- tion of 31.5 dB. Attenuation accuracy is excellent at 0.25 dB typical step error with an IIP3 of +50 dBm. un tt Six bit serial control words are used to select each attenuation state. A single Vcc bias of +5V is required. Electrical Specifications, T = +25 C, with Vcc = +5V A Parameter Frequency (GHz) Min. Typ. Max.
