Product Details

The HMC1119 is a broadband, highly accurate, 7-bit digital attenuator, operating from 0.1 GHz to 6.0 GHz with 31.5 dB attenuation control range in 0.25 dB steps.

The HMC1119 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 Ω and do not require any external matching components. The design is bidirectional; therefore, the RF input and output are interchangeable.

The HMC1119 has an on-chip regulator that can support a wide supply operating range from 3.3 V to 5.0 V with no performance change in electrical characteristics. The HMC1119 incorporates a driver that supports serial (3-wire) and parallel controls of the attenuator.

The HMC1119 comes in a RoHS-compliant, compact, 4 mm × 4 mm LFCSP package.

A fully populated evaluation board is available.
