re: Improving your TX side or your RX side: which makes more sense?

NO RATINGS
In my opinion, receiver side is more sensitive, since one have very limited control on receiving signal.

NO RATINGS
It's usually the transmit side, if you can do it, that's most useful. Even cheap receiver designs can manage a 3dB NF these days, and with the best will in the world, you won't improve that by more than 2dB - and at that, depending to some extent on the band in use, you'll be limited in fact by atmospheric and solar noise coming in the antenna.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
