Abstract

In earlier work⁽¹⁾ we showed that the dependence of the gain of a transphasor amplifier on the modulation frequency of the input signal is characterised by an effective time constant τ_e, thus: - giving a bandwidth Δv = l/2πτ_e (corresponding to |G| = G₀√2). The dependence of G₀, the low frequency gain, on τ_e indicated a constant gain-bandwidth product. However, by Including the full cavity parameters and calculating the absolute value for G₀ we now show that this is not strictly the case.
