Overview
The HMC1119LP4ME, produced by Analog Devices Inc., is a broadband, highly accurate 7-bit digital attenuator. It operates over a frequency range of 0.1 GHz to 6.0 GHz, offering a 31.5 dB attenuation control range in 0.25 dB steps. This device is implemented in a silicon process, providing fast settling time, low power consumption, and high ESD robustness. The HMC1119 is designed for excellent step accuracy and high linearity over frequency and temperature ranges. It features internally matched RF input and output to 50 Ω, eliminating the need for external matching components, and is bidirectional, allowing the RF input and output to be interchangeable.
