The bandwidth of LTE-TDD B41 for SC606T-EM, SC606T-JP, SC606T-NAD is 200 MHz (2496–2690
MHz), and the corresponding uplink EARFCN ranges from 39650 to 41589.
6.1.1. Reference Design for Main and Rx-diversity Antenna Interfaces
A reference circuit design for the main and Rx-diversity antenna interfaces is shown as below. A π-type
matching circuit should be reserved for both ANT_MAIN and ANT_DRX for better RF performance, and
the π-type matching components (R1/C1/C2, R2/C3/C4) should be placed as close to the antennas as
possible. The capacitors are not mounted by default and the resistors are 0 Ω.
