Programming Registers Sequence for MAX2871

Official Hardware Mega Due

I need clarification about the register writing sequence for MAX2871 through SPI protocol. As per the details given in the datasheet I have followed the below-given sequence.

for(int i = 0; i<2;i++){

writeRegisterValue5 = 0x00400005;
writeRegisterValue4 = 0x601640DC;

writeRegisterValue3 = 0x0000F233;

writeRegisterValue2 = 0x0C009F42;

writeRegisterValue1 = 0x400083E9;

writeRegisterValue0 = 0x00960000;

delay(20); // 20ms Delay

};

writeRegisterValue4 = 0x6180B33C; // Enabled RFOUTA & RFOUTB

I have observed that the MUX is getting changed according to the set MUX registers. But there was no RF output. Provided RFOUT_EN pin is pulled HIGH.

  1. Is there any option to check if the RFOUTA/B is set or not?

  2. Is the above-mentioned sequence correct?
