HMC1119 Digital Step Attenuators

Analogue Devices HMC1119 Digital Step Attenuators are broadband, 7-bit attenuators covering 0.1-6.0GHz with a 31.5dB attenuation control range in 0.25dB steps. The HMC1119 driver supports serial (3-wire) and parallel controls of the attenuator. The attenuators are optimised for excellent step accuracy and high linearity over frequency and temperature range. The devices maintain excellent attenuation accuracy of ±0.2dB with a ±0.1dB typical step error. HMC1119's safe-state transitions feature ensures safe operation of the components in the RF signal chain. Designed using an advanced silicon process, the HMC1119 attenuators offer low power consumption, fast settling time, and high ESD robustness. An on-chip regulator supports a wide, 3.3-5.0V single-supply operating range with no performance degradation in electrical characteristics. The device's ~100nsec switching and 0.05dB in ~250nsec settling times make the HMC1119 attenuators ideal for fast-switching applications and time division multiplexed systems. The robust 2kV ESD protection on signal inputs and outputs complies with the most stringent RF applications and assembly requirements.
