HMC1119LP4ME

衰减器 7-bit 0.1-6Ghz DATT

0.25 dB LSB, 7-Bit, Silicon Digital  Attenuator, 0.1 GHz to 6.0 GHz

GENERAL DESCRIPTION HMC1119LP4ME

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.
