FMC30RF User Manual

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.
