Balanced Phase Detectors

QuinStar Technology's QEP series balanced phase detectors enable phase comparison of two RF signals. They utilize GaAs beam lead diodes which offer significant advantages over other detector types. The diodes are carefully matched to achieve high isolation between RF ports, low DC offset, noise cancellation, and suppression of the adverse effect of amplitude modulation. The detected output is proportional to phase differences up to 180 degrees for two equal amplitude signals at the same frequency. Balanced phase detectors are typically used in phase bridges and phase modulated receiver systems.
