HMC1119LP4METR

HMC1119 is a broadband, highly accurate, 7bit digital attenuator, operating from 0.1GHz to 6GHz with 31.5dB attenuation control range in 0.25dB steps. It is implemented in a silicon process, offering very fast settling time, low power consumption, and high ESD robustness. The device features safe state transitions and is optimized for excellent step accuracy and high linearity over frequency and temperature range. The RF input and output are internally matched to 50 ohm and do not require any external matching components. The design is bidirectional; therefore, the RF input and output are interchangeable. It is used in applications such as cellular infrastructure, microwave radios and very small aperture terminals (VSATs), test equipment and sensors, IF and RF designs etc.
