PRELIMINARY
Certain widely–spaced combinations of A–Band transmit
frequencies, when combined to drive one antenna, can
produce 3rd order intermodulation products that are within
the receive band. During system planning, the proper
selection of combined frequencies or the use of multiple
transmit antennas will prevent this situation. Additional
receive filtering at a particular cell site can also help. China
A Band is used in the China SC480–800 BTS in
conjunction with a GSM Elimination Filter.
