The AFE5401-EP is a quad-channel, analog front-end (AFE), targeting applications where the level of integration is critical. Each channel comprises a complete base-band signal chain with:
- A low-noise amplifier (LNA),
- A programmable equalizer (EQ),
- A programmable gain amplifier (PGA), and
- An antialias filter (AAF)
- A high-speed, 12-bit, analog-to-digital converter (ADC) that samples at 25 MSPS per channel.
Having four integrated signal chain channels enables the device to be used in different end-use systems such as:
- Automotive radar (where a down-converted base-band signal from an RF front-end can be applied to the inputs of the AFE)
- Applications where up to 12-MHz voltage signal is available from a transducer
