Page 10: Reference Design
SIM8200EA_M2 Antenna Port Mapping and Deign Guide 3.2 Reference Design The space isolation of each antenna should be larger than 20dB. And the isolation between LTE antennas and 5GNR antennas is at least 15dB, and the GNSS antenna between 4G/5G antennas should be larger than 15dB. -
Page 11: Antenna Requirements
SIM8200EA_M2 Antenna Port Mapping and Deign Guide (4) And the RF trace ground should be complete; (5) RF device should place ground to the nearest ground plane; (6) Between RF trace and below should avoid other signal trace or parallel trace to the RF signal. (7) Recommend to more ground vias near the RF traces. - Page 12 SIM8200EA_M2 Antenna Port Mapping and Deign Guide Figure3 Triplexer characteristic In this program, the max downlink throughput for n79/n41 changes to half, and quarter for n77/n78. the max uplink throughput for n79/n77/n78 changes to half, n41 is not affected. Figure4 Triplexer and Antenna connection 5.2 Four antennas design For China Mobile (CMCC) only, the NR band need n41 and n79, if customer want to use less antennas, at least 4 Antennas should be used, they are ANT0, ANT1, ANT4, ANT7.

- Page 14 SIM8200EA_M2 Antenna Port Mapping and Deign Guide 5.3 Six antennas design If customers want to use all the China NR bands, and want to use less Antennas than the original design which use 8 Antennas. The six antennas configuration is recommended. Like the 2 Ants design, ANT4, ANT5 and ANT7 should be combine to with a triplexer, the triplexer detail please refer to 2 antennas design.
