Note: Isolation specification max limit set to ensure at least 20dB of isolation. Calculation example: P_OUT@A_NT-P_OUT@RXPort, Lo Band
Isolation=33-10=23dB, Hi Band Isolation=30-10=20dB. Additional RX3 circuitry ensures specification for Hi Band TX-RX overlapping
frequencies. Lo Band RX-RX overlapping frequencies has sufficient margin.
