The demerits of balanced mixers are their requirement of greater LO power.

Extended single sideband eSSB [ ] Extended single sideband is any SSB-SC mode that exceeds the audio bandwidth of standard or traditional 2.

This results in direct floating-carrier modulation in a radio frequency amplifier in which the amplitude-modulated and phasemodulated components are amplified and recombined.

Practical implementations [ ] A , an early Amateur Radio transceiver that featured SSB voice capability Bandpass filtering [ ] One method of producing an SSB signal is to remove one of the sidebands via , leaving only either the upper sideband USB , the sideband with the higher frequency, or less commonly the lower sideband LSB , the sideband with the lower frequency.

The currents in the upper and lower parts each produce a magnetic field that is both equal and opposite with each other therefore, the magnetic fields produced cancel out and the carrier is suppressed.

For the input and output transformers, a 1:2 turns ratio is needed.

At some point, a DSBSC signal needs to have its carrier signal regenerated to allow for the signal to be put back into its original form for reception.

Operation The diodes used in the diode ring modulator can either be silicon, silicon Schottky-barrier or gallium-arsenide.

The output, however, is measured at the secondary of the output transformer.

2A is an enlarged perspective view of the single balanced beam vibratory element of FIG.

As a result, frequencies at or near the carrier frequency remain available at the output.
