5.1.3. Reference Design of RF Antenna Interfaces

A reference design of ANT_MAIN, ANT_DIV, ANT_MIMO1 and ANT_MIMO2 interfaces is shown as
below. It should reserve a π-type matching circuit for better RF performance. The π-type matching
components (R1/C1/C2, R2/C3/C4, R3/C5/C6, R4/C7/C8) should be placed as close to the antennas as
possible and are mounted according to the actual debugging. C1~C8 are not mounted and a 0Ω resistor
is mounted on R1~R4 respectively by default.
