AD9870 Description
The AD9870 is a general-purpose IF subsystem that digitizes a low-level 10 MHz 300 MHz IF input with a bandwidth of up to 150 kHz. The signal chain of the AD9870 consists of a low-noise amplifier, a mixer, a variable gain amplifier with integral antialias filter, a bandpass sigma-delta analog-to-digital converter, and a decimation filter with programmable decimation factor. An automatic gain control (AGC) circuit...
