8.1.4 Long Range low external Bill of Material

This design delivers the minimum achievable external eBOM for a +22 dBm Sub-GHz solution by eliminating the external RF switch through a switchless dual-PA architecture. The result is a cost-optimized, long-range reference design with no sacrifice in transmit performance.

  • +22 dBm maximum TX power with a switchless architecture
  • Robust in the presence of 5G base stations
  • Long-range capability at minimum BOM cost — no performance trade-off required
