초록 ▼

A compact local oscillator network for use in a quadrature modulator and/or demodulator is presented. Single side band circuitry is configured to produce quadrature signals with a high degree of accuracy such that two equal amplitude signals are generated having a precise 90°phase difference. The network accuracy is substantially not affected by phase or amplitude imbalances within or introduced into the network. For example, the network may include: a first quadrature circuit for dividing a first input signal into a first in-phase signal and a first quadrature signal 90°out of phase; a second quadrature circuit for dividing a second input signal into a second in-phase signal and a second quadrature signal 90°out of phase; a first mixer for mixing said first in-phase signal and said second in-phase signal; a second mixer for mixing said first quadrature signal and said second quadrature signal; a third mixer for mixing said first quadrature signal and said second in-phase signal; a fourth mixer for mixing said first in-phase signal and said second quadrature signal; a first combiner for combining the outputs of said first and second mixers into a first combiner for combining the outputs of said first and second mixers into a first local oscillator output signal; and a second combiner for combining the outputs of said third and fourth mixers into a second local oscillator output signal.
