Guidelines of controlling tuneable gain and attenuators are provided in section 6. The
maximum input level at the RF input is +3dBm and can be applied to the board when the total
gain of the analog line-up is set to minimum. This is done by:
-
Bypass LNA2
-
Set the stepped attenuator to 32dB attenuation
-
Set the BB gain of the TRF3711 to 0dB (default setting is 15dB, refer to the
datasheet of the TRF3711)
Applying a signal of +3dBm to the first stage LNA drives the LNA close to its input 1dB
compression point.
