Overview
The HMC1119LP4METR is a highly accurate, 7-bit digital attenuator produced by Analog Devices Inc. This component operates over a broad frequency range from 0.1 GHz to 6.0 GHz, offering a 31.5 dB attenuation control range in 0.25 dB steps. It is implemented in a silicon process, ensuring 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 ranges. The RF input and output are internally matched to 50 Ω, eliminating the need for external matching components, and the design is bidirectional, allowing the RF input and output to be interchangeable.
