TX and RX gains in osmocom and amplifiers in bladeRF
Posted: Sun Mar 05, 2017 11:09 am
Hi.
I haven't found information about the relationship between blade gain in the different stages and osmocom gains
In bladeRF gains are set by the LMS6002D, so we have
Transmision
TXLPF gain: 0 or 6dB
TXVGA1 gain: 0 to 31dB in 1dB step
TXVGA2 gain: 0 to 25 dB in 1dB step
Reception
RXLNA gain: 0 or 6dB
RXVGA1 gain: 0 to 25 dB in 1 dB step
RXLPF gain 0 or 6dB
RXVGA2 gain 0 to 30 dB in 3 dB step
In a osmocom source or osmocom sink we have
BB gain
IF gain
RF gain
The relationship between BladeRF gains and osmocom gains may be ........ ??????
BB gain -> RXVGA2,
IF gain -> RXVGA1, TXVGA1
RF gain -> RXLNA, TXVGA2
and the LPF gain??
regards
