HMC1122 - Silicon Digital Attenuator

Description

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.

Features

  • Attenuation range: 0.5 dB LSB steps to 31.5 dB Low insertion loss 1.1 dB at 1 GHz 1.3 dB at 2 GHz Typical step error: less than ±0.1 dB Excellent attenuation accuracy Safe state transitions High linearity Input 0.1dB compression (P0.1dB): 30 dBm typical Input third-order intercept (IP3): 55 dBm typical RF settling time (0.05 dB final RF output): 250 ns Low phase shift error: 6° at 1 GHz Single supply operation: 3.3 V to 5 V ESD rating: Class 2 (2 kV HBM) 24-lead, 4 mm × 4 mm LFCSP package: 16 mm.
