1 dB LSB GaAs MMIC 5-BIT DIGITAL POSITIVE CONTROL ATTENUATOR, DC - 3 GHz Eval PCB

Evaluation Board, 5Bit Digital Attenuator

Eval Board HMC470LP3 Digital Attentuator

The HMC470LP3(E) is a broadband 5-bit GaAs IC digital attenuator in low cost lead-less surface mount package. This single positive control line per bit digital attenuator incorporates off chip AC ground capacitors for near DC operation, making it suitable for a wide variety of RF and IF applications. Covering DC to 3 GHz, the insertion loss is less than 1.5 dB typical. The attenuator bit values are 1 (LSB), 2, 4, 8, and 16 dB for a total attenuation of 31 dB. Attenuation accuracy is excellent at ±0.3 dB typical step error with an IIP3 of +45 dBm. Five TTL/CMOS control inputs are used to select each attenuation state. A single Vdd bias of +5V is required. Applications Cellular; UMTS/3G Infrastructure ISM, MMDS, WLAN, WiMAX Microwave Radio & VSAT Test Equipment and Sensors
