HMC792ALP4E v00.0613 0.25 LSB GaAs MMIC 6-BIT DIGITAL ATTENUATOR, DC - 6 GHz Typical Applications Features The HMC792ALP4E is ideal for: 0.25 dB LSB Steps to 15.75 dB Power-Up State Selection Cellular/3G Infrastructure High Input IP3: +53 dBm WiBro / WiMAX / 4G Low Insertion Loss: 1.8 dB 2.0 GHz Microwave Radio & VSAT TTL/CMOS Compatible, Serial, Parallel Test Equipment and Sensors or Latched Parallel Control IF & RF Applications 0.1 dB Typical Step Error Single +3V or +5V Supply 2 24 Lead 4x4mm SMT Package: 16mm Functional Diagram General Description The HMC792ALP4E is a broadband 6-bit GaAs IC Digital Attenuator in a low cost leadless SMT package. This versatile digital attenuator incorporates off-chip AC ground capacitors for near DC operation, making it suitable for a wide variety of RF and IF applications. The dual mode control interface is CMOS/TTL com- patible, and accepts either a three wire serial input or a 6 bit parallel word. The HMC792ALP4E also features a user selectable power up state and a serial output port for cascading other Hittite serial controlled components. The HMC792ALP4E is housed in a RoHS compliant 4x4 mm QFN leadless package, and requires no external matching components. Electrical Specifications, T = +25 C, Vctl = 0/+Vdd A Min. Typ. Max. Min. Typ.
