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.
