MT6179 Transceiver Supported Band

MT6179 LNA Mapping

--PRx + DRx: 24+24 ports
--LB: <1GHz. L/MB:<1G, 1.45~2.2GHz. MB/HB:1.8~2.7GHz. 
--UHB: 2.3-2.7 3.4-3.8GHz. UNII: 5.2~5.9GHz.
--Supports 2G SAWless (B2,3,5,8) and TDS/LTETDD SAWless(B34,B39)

MT6179 RX port allocation for global SKU

Please follow the rule if you want to change LNA port:
• Bands only support non-CA: follow LNA frequency range 
• Bands with CA: intra-group changeable
• PRX & DRX MUST be in the same LNA Group
