Introduction

The HMC424ACHIPS is a broadband, 6-bit, gallium arsenide (GaAs), digital attenuator monolithic microwave integrated circuit (MMIC) chip with a 31.5 dB attenuation control range in 0.5 dB steps. The HMC424ACHIPS offers excellent attenuation accuracy of ±(0.2 dB + 3% of attenuation state) and high input linearity over the specified frequency range from 0.1 GHz to 13.0 GHz with a typical insertion loss of ≤4.2 dB. The attenuator bit values are 0.5 dB (LSB), 1 dB, 2 dB, 4 dB, 8 dB, and 16 dB for a total attenuation of 31.5 dB with a ±0.5 dB of typical step error. The device allows a user to program the attenuation state via six parallel control inputs toggled between 0 V and VEE. The HMC424ACHIPS operates with a single negative supply voltage from -3 V to -5 V, and requires an external driver to interface with a CMOS/transistor to transistor logic (TTL) interface. The HMC424ACHIPS comes in a RoHS compliant, 9-pad bare die.
