Detector system with adjustable phase stage |
摘要 |
A detector system has a local oscillator port, a radio frequency port, and an oscillator providing a local oscillator signal having amplitude-modulated (AM) noise coupled. A first detector detects the local oscillator signal and produces a first detected signal having a first detected AM noise signal component and a demodulated signal component at a first phase. A second detector detects a second high-frequency signal to produce a second detected signal having a second detected AM noise signal component at a second phase. An algebraic combining network combines the first detected signal and the second detected signal to produce a demodulated signal component at an output. A phase delay disposed between the local oscillator and the output of the algebraic combining network is calibrated to offset the first phase from the second phase to improve signal-to-noise ratio at the output. |
