Any recent E-band radio will be at least QPSK and uses a 1 GHz wide channel. The old first generation Bridgewave, E-band and Gigabeam products were, if I recall right, 5 GHz wide each direction.
Newer stuff is capable of operating at 16QAM and/or 64QAM in even smaller channels for real 1 Gpbs FDD, but is very susceptible to rain. You need quite a strong signal to maintain 64QAM modulation vs. what you can do with a 1GHz-wide, QPSK modulated Bridgewave link that has a +18 or +19 Tx power. It doesn't help that the Siklu radios are only +8. Current Bridgewave or Siklu 80 GHz links use a single polarity for 1Gbps FDD. You can install a setup with two dishes, four radio heads and two OMTs and operate in both polarities for 2 Gbps FDD. Or you can buy the new 3 Gbps Bridgewave radio which is $$$$$$. I assume you're asking about 70/80 for use in PR, which is a really bad rain zone... You'll be limited to very short distances even with +19Tx power radios and 52dBi gain dishes, if you want a statistical five nines link availability/uptime over a full year.
