BA3833F
The BA3833F is a 4+1 band-pass filter IC for spectrum analyzer w ith built-in recording indicator output.
External components can be reduced largely by incorporating all capacitors that compose a filter. This enables to make
set smaller and more highly-reliable.
zApplications zExternal dimensions (Unit : mm)
