GENERAL DESCRIPTION

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 device allows a user to program the attenuation state via six

parallel control inputs toggled between 0 V and V_EE.

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 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 HMC424ACHIPS comes in a RoHS compliant, 9-pad bare die.
