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. |
