HMC624A - Analog Devices

HMC624A GaAs Digital Attenuator

The HMC624A is a 6-bit digital attenuator with a 31.5 dB attenuation control range in 0.5 dB steps. The HMC624A 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.
