Desired S1 Signal Level and LO Phase Noise Requirements in HF Transceivers : JA2GXU
1. Required LO phase noise equation for HF Receiver and Transceiver Emmanuel Ngompe described reciprocal mixing effects for the required LO phase noise equation, modified for HF receiver configurations which direct sampling SDR, direct conversion, single conversion, double conversion and triple conversion. L(Δfc) [dBc/Hz] = Sdes－Sbl(Δfc)－C/Ireq－10log(BW)－MN L(Δfc): phase noise...
MRSL(Minimum Readable Signal Level) for HF Transceivers and low phase noise requierments in LO or Clock : JA2GXU
Introduction My friend of Ham radio operator said receiving desired weak signal readability ranking are DS_SDR > TS-590 > FTdx5000 at 20m band and low band (80m and 40m), and other ham said receiving desired weak signal readability ranking are TS-590 > FTdx5000 at low band (80m and 40m), however...
