There are a multiplicity of transmission modes both new and old at the disposal of a radio amateur, but the leader of the pack is still single-sideband or SSB. An SSB transmitter emits the barest ...

Abstract: A wavelength-independent single sideband (SSB) transmitter for high-performance radio-over-fiber links is proposed. Third order intermodulation distortion improvement of 9 dB is ...

Abstract: 100 G/λ amplifier-free direct detection (DD) systems beyond 40-km reach are desirable to enable the next generation cost- and power-efficient 800 G-ER optical modules. Though such systems in ...

Most amateur radio operators prefer to operate on SSB (single sideband) and CW because these carry the signal over a long distance for a given transmitter power. Broadcast receivers are not meant to ...

LASER COMPONENTS supplies the ModBox-CBand-CS-SSB which is an Optical Transmitter Frequency shifter based on high order optical Carrier Suppressed Single Side Band modulation. The ModBox operates in ...

The goal of the TechNight Radio Project is to design and build a simple, low cost, low power, yet high quality single band ham transceiver. One of the requirements is the ability to use FT-8 and the ...
