HMC1119LP4METR

La description

The HMC***9 is a broadband, highly accurate, *-bit digital attenuator, operating from 0.1 GHz to 6.0 GHz with *1.5 dB attenuation control range in 0.*5 dB steps. The HMC***9 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 and output are internally matched to *0 Ω and do not require any external matching components. The design is bidirectional; therefore, the RF and output are interchangeable. 
The HMC***9 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 HMC***9 incorporates a driver that supports serial (*-wire) and parallel controls of the attenuator. The HMC***9 comes in a RoHS-compliant, compact, 4 mm × 4 mm LFCSP package. A fully populated evaluation board is available.
