Hi,
I am trying to receive a 1MHz bandwidth signal with a 1090MHz carrier frequency, since I am not an expert in RF and microwave, i would like to ask you if my current circuit configuration can receive and demodulate the 1090MHz signal using 3 LNAs and ADL5513 in the output, and if a balun is mandatory before the ADL5513. Thanks !
The configuration is as follow :
RFIN -> SAW Filter (SF2321D) -> LNA (AD8354) -> LNA (MAX2640EUT) -> SAW Filter (SF2321D) -> LNA (AD8354) -> SAW Filter (SF2321D) -> Balun (ETC1-1-13TR) -> Envelope detector (ADL5513) -> ADC
Thanks !
