At the RN, the downlink signal is combined with the coming P2P light from BS_1 by a 33/66-GHz optical interleaver (IL) to realize single sideband
transmission for the two signals.
There is the hiss of the burner, and the single sideband
radio is on.

scheme and its application in a 60-GHz full duplex ROF system," IEEE Photonics Technology Letters, vol.
The SGAs also provide a typical single sideband
phase noise specification of -135 dBc/Hz at 20 kHz offset from a 1-GHz carrier, 1-ms settling times in the conventional frequency selection mode or 100 [mu]s in the list mode, and + 13-dBm maximum RF output power with 0.01-dB resolution.
In particular, the company's microwave and millimeter-wave mixer ICs have been used to implement image reject mixer (IRM) and single sideband
(SSB) upconverter circuits.
However, single sideband
modulation is particularly challenging because the carrier is suppressed, so the received signal strength rises and falls with modulation.
Features include an advanced synthesizer-based design, one-button autotuning, channel power measurements, peak search, marker measurement, switchable 50-[ohm] or 75-[ohm] input impedance, single sideband
phase noise of -90 dBc @ 100 Hz offset, and a built-in RS-232 interface.
Its single sideband
(SSB) phase noise is typically -135 dBc at 1 GHz (20 kHz offset, 1 Hz measurement bandwidth).
The AIP method even suppresses the feed through on single sideband
signals, and consequently the intelligence on the signal can be detected while the system is deriving the bearing angles.
Detailed digital modulation analysis is not possible, but the unit does perform amplitude modulation, frequency modulation, and single sideband
(AM/FM/SSB) demodulation and has the capability to identify common signal types by their bandwidth and spectrum skirt shape as an aid to determining the sources of interference.

A sample of the radar LO is used with the synthesized signals in phase-locked loops to generate the desired Doppler shifted clutter and target are used rather than single sideband
modultion of the radar transmitted signal to reduce the spurious signals in the output.
