The EVAL-CN0259-HSCZ is an evaluation board described in the circuit from lab CN-0259, entitled "High performance 65MHz bandwidth quad IF receiver with antialiasing filter and 184.32MSPS sampling rate". The circuit is a 65MHz bandwidth receiver front end based on the ADL5565 ultrahigh dynamic range differential amplifier driver and the 11-bit, 200MSPS AD6657A quad IF receiver. The fourth-order butterworth antialiasing filter is optimised based on the performance and interface requirements of the amplifier and IF receiver. The total insertion loss due the filter network and other resistive components is only 2dB. The overall circuit has a bandwidth of 65MHz, with the low-pass filter having a 1dB bandwidth of 190MHz and a 3dB bandwidth of 210MHz. The pass-band flatness is 1dB. The circuit is optimised to process a 65MHz bandwidth IF signal centered at 140MHz with a sampling rate of 184.32MSPS.
