HMC1095LP4E v00.0613 Attenuators - SMT 0.5 dB LSB GaAs MMIC 6-BIT 75 Ohms DIGITAL ATTENUATOR, DC - 3 GHz Typical Applications Features The HMC1095LP4E is ideal for: 0.5 dB LSB Steps to 31.5 dB • CATV/ Satellite Set Top Boxes Power-Up State Selection • CATV Modems High Input IP3: +57 dBm • CATV Infrastructure Low Insertion Loss: 1.5 dB @ 1.0 GHz • Data Network Equipment TTL/CMOS Compatible, Serial, Parallel or Latched Parallel Control ±0.25 dB Typical Step Error Single +3V or +5V Supply 24 Lead 4x4mm SMT Package: 16mm2 Functional Diagram General Description The HMC1095LP4E 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 compatible, and accepts either a three wire serial input or a 6 bit parallel word. The HMC1095LP4E also features a user selectable power up state and a serial output port for cascading other Hittite serial controlled components. The HMC1095LP4E is housed in a RoHS compliant 4x4 mm QFN leadless package, and requires no external matching components.
