6-channel RF-sampling receiver, 5-MHz to 12-GHz, max 1200-MHz IBW

The AFE7906 is a high

performance, wide bandwidth multi-channel receiver, integrating six RF Sampling

ADCs. With operation up to 12GHz, this device enables direct RF sampling in the L,

S, C and X-band frequency ranges without the need for additional frequency

conversions stages. This improvement in density and flexibility enables

high-channel-count, multi-mission systems.

Each receiver chain includes a 25dB range DSA

(Digital Step Attenuator), followed by a 3GSPS ADC (analog-to-digital converter).

Four receiver channels have an analog peak power detector and various digital power

detectors to assist an external or internal autonomous automatic gain controller,

and RF overload detectors for device reliability protection. Flexible decimation

options provide optimization of data bandwidth up to 1200MHz for four RX or

600MHz.

The device contains a SYSREF timing detector to allow optimization of the SYSREF input timing relative to the device clock.
