The block is the 4rd order Butterworth low pass filter with cut-off frequency adjustment (22...50 MHz ). High third-order input intercept point is reached due to using a pseudodifferential circuit and Sallen-Key circuit. There are two modes for cut-off frequency programming: manually and automatically. The generator is used to adjust filter cut-off (CO) frequency in automatic mode. Also CO frequency can be set manually.
