Standard Frequency Band Settings

The following tables show SF switch settings that would provide the appropriate passband frequency response
required for specific SF bands. Note that the passband response may be different than the filter bandwidth of the
miniRepeater. In these instances, the miniRepeater high rejection filter is used in conjunction with the duplexer
response to narrow the actual band-pass response.
