●Product Details
●The HMC470A is a 5-bit digital attenuator with a 31 dB attenuation control range in 1 dB steps.
●The HMC470A offers excellent attenuation accuracy and high input linearity over the specified frequency range from 100 MHz to 3 GHz. However, this digital attenuator features ACG pins for external ac grounding capacitors to extend the operation below 100 MHz.
●The HMC470A operates with a single positive supply voltage from 3 V to 5 V and provides CMOS-/TTL-compatible parallel control interface by incorporating an on-chip driver. The HMC470A comes in a RoHS compliant, compact, 3 mm × 3 mm LFCSP package.
