IF-LO delay mismatch and noise reduction in transposed gain oscillators

This paper describes delay mismatch effects in transposed gain oscillators. Unequal time delay between IF and LO signal paths give rise to sub- optimum local oscillator´s noise suppression. It is also shown that the phase response of the transposed gain amplifier is a function of LO signal path and optimum delay matching may not give a condition for oscillation.
