Schematic example
This chapter explains circuit examples of each frequency bands. It is necessary to adjust values depending on customers’
board pattern and parts. Please note the following for board design.
⚫
Fix REGPDIN(#12) pin and TEST(#39) pin to GND at the normal operation.
⚫
Fix RF_AMON(#5) pin to OPEN.
⚫
When using TCXO, fix RF_XIN(#1) pin to OPEN. Refer section 3.TCXO circuit.
⚫
When not using 2.4GHz band, fix RF_LNA_IN2(#37), RF_PA_OUT2(#38) to OPEN. Parts connecting above 2
pins are unnecessary.
⚫
When not using SubGHz band, fix RF_REG_PA(#32), RF_PA_OUT1(#33),RF_LNA_IN1_N(#34),
RF_LNA_IN1(#35) to open. Parts connecting to above 4 pins are unnecessary.
⚫
When not using DCDC, change L1 to 0Ω.
