AFE7444 Description
The AFE7444 is a quad-channel, wideband, RFsampling analog front end (AFE) based on 14-bit, 9GSPS DACs and 14-bit, 3-GSPS ADCs. With operation at an RF of up to 6 GHz, this device enables direct RF sampling into the C-band frequency range without the need for additional frequency conversions stages. This improvement in density and flexibility enables high-channel-count, multimission systems.
