HMC1122LP4ME

衰减器 6-Bit Attenuator 2mm series device w/re

0.1 GHz to 6.0 GHz, 0.5 dB LSB, 6-Bit,  Silicon Digital Attenuator

GENERAL DESCRIPTION HMC1122LP4ME

The HMC1122 is a 6-bit digital attenuator operating from

0.1 GHz to 6 GHz with a 31.5 dB attenuation control range in

0.5 dB steps.

The HMC1122 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

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.
