Advisory 19

Single-ended mode operation might cause sensitivity degradation at some temperatures

Revision Affected:

A and B

Details:

When operating the device in single-ended mode, the sensitivity might degrade at some temperature levels with the default LNA bias setting, LNA_IB_OFFSET = +3.

Workaround:

An offset value of -1 is recommended to use for operation from -20°C to 85°C. For operation below -20°C an offset value of -2 is recommended.

Replace the existing override:

// Set LNA IB offset to 0x03 (+3)
(uint32_t)0x00038883

With an offset value of -1:

// Set LNA IB offset to 0xFF (-1)
(uint32_t)0x00FF8883

With an offset value of -2:

// Set LNA IB offset to 0xFE (-2)
(uint32_t)0x00FE8883
