A single-sideband suppressed-carrier ferrite modulator is used in a Qband serrodyne phase bridge. By suitably processing the bridge-detector output, relative phase in the unknown bridge arm may be measured to within 1% of its true value, despite nonlinearities in both the static insertion-loss and phase-shift characteristics of the modulator. The modulator drive is not critical.
