5-3-15 Beam Former Board(s), BF-64
5-3-15-1 General Description, BF-64 boards
The BF64 board converts the analog RF-input signal from 64 receiver channels into digital form and
performs receiver focusing and steering by digital delay.
All digital signal processing to filter and delay each channel is performed in an Application Specific
Integrated Circuit (ASIC) named FOC32.
The output of this board is either connected to a new BF64 board (to increase the number of channels)
or to the RFT or RFI board for digital RF processing.
