DC-30 GHz 6-Bit Digital Attenuator: CMD325
Source: Custom MMIC
The CMD325 from Custom MMIC is a negative controlled, wideband GaAs MMIC 6-bit digital attenuator die designed to operate from the DC to 30 GHz frequency range. Each bit of the attenuator is controlled by a single voltage of either 0 V or –5 V. It features a low insertion loss of 4 dB at 12 GHz and the attenuation accuracy is typically 0.2 dB step error.
The CMD325 bit values are 0.5 (LSB), 1, 2, 4, 8 and 16 dB, for a total attenuation of 31.5 dB. It has a 50 ohm matched design which eliminates the need for RF port matching and offers full passivation for increased reliability and moisture protection.
