GENERAL DESCRIPTION
The HMC624A-EP is a 6-bit digital attenuator with a 31.5 dB
attenuation control range in 0.5 dB steps.
The HMC624A-EP offers excellent attenuation accuracy and
high input linearity over the specified frequency range from
100 MHz to 6.0 GHz. However, this digital attenuator features
external ac grounding capacitors to extend the operation below
100 MHz.
The HMC624A-EP is integrated with two dies: a CMOS driver
and a gallium arsenide (GaAs) RF attenuator. The CMOS driver
provides both serial and parallel control of the RF attenuator.
The device also features a user-selectable power-up state and a
serial output port for cascading other serial controlled
components.
The HMC624A-EP operates with a single positive supply
voltage from 3 V to 5 V and provides a CMOS-/TTL-
compatible control interface.
The HMC624A-EP comes in a RoHS compliant, compact,
4 mm × 4 mm LFCSP package.
Additional application and technical information can be found
in the HMC624A data sheet.
