REGISTER 9—AGC REGISTER
Register 9—AGC Register Comments
• The recommended AGC threshold settings are AGC_LOW_THRESHOLD = 15, AGC_HIGH_THRESHOLD = 79.
• AGC high and low settings must be more than 30 apart to ensure correct operation.
• LNA gain of 30 is available only if LNA mode, R6_DB15, is set to 0.
The default settings (that is, if this register is not programmed) are AGC_LOW_THRESHOLD = 30,
default AGC_HIGH_THRESHOLD = 70. See the RSSI/AGC section for details.
