GENERAL DESCRIPTION
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.
