HMC542BLP4E v00.1212 0.5 dB LSB GaAs MMIC 6-BIT DIGITAL SERIAL CONTROL ATTENUATOR, DC - 4 GHz Typical Applications Features the HMC542BlP4e is ideal for: 0.5 dB LSB Steps to 31.5 dB t • Cellular/PCS/3G Infrastructure TTL/CMOS Compatible Serial Data Interface M • ISM, MMDS, WLAN, WiMAX, & WiBro SPI Compatible Serial Output s ± 0.25 dB Typical Step Error • Microwave Radio & VSAT - Single +5V Supply l • Test Equipment and Sensors A 24 Lead 4x4 mm QFN Package: 16 mm² t i g Functional Diagram General Description Di The HMC542BLP4E is a broadband 6-bit GaAs IC digital attenuator with a CMOS compatible serial - to parallel driver in low cost leadless surface mount s package. This serial control digital attenuator incorp r rates off chip AC ground capacitors for near DC opera- o tion, making it suitable for a wide variety of RF and t A IF applications. Covering DC to 4 GHz, the inser- u tion loss is 1.7 dB and the attenuator bit values are n 0.5 (LSB), 1, 2, 4, 8, and 16 dB for a total attenua- e tion of 31.5 dB. Attenuation accuracy is excellent at t ±0.25 dB typical step error with an IIP3 of +50 dBm. t Six bit serial control words are used to select each A 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.
