Document Type and Number:
Japanese Patent JP4213374
Kind Code:
B2
Abstract:
Amplifier arrangement comprising : a resistive receive hybrid means adapted to pass a combination of a received signal and a transmitted signal, a resistive transmit hybrid means adapted to pass substantially only the transmitted signal, a tuneable gain means adapted for converting the transmit hybrid signal into a signal corresponding substantially to the reverse of the portion of the receive hybrid signal function of the transmitted signal passing through the receive hybrid means, signal treatment means adapted to add or subtract the gained signal to and/or from the receive hybrid signal, whereby said treatment is adapted for generating a signal which is substantially independent of the transmitted signal.
