The first stage:
gain:18dB, NF:9dB, 1dB point:-16dBm, RF-LO and LO-IF isolation:45dB, RF-IF:75dB
The second stage:
gain:27dB, NF:5dB, RF-LO and LO-IF isolation:45dB, RF-IF:75dB
The third stage:
gain:75dB, NF:3dB, RF-LO and LO-IF isolation:45dB, RF-IF:75dB
Should I choose which type of mixer?Gilbert mixer?The three mixers don`t need to be the same.
