Abstract :
A one chip bipolar amplitude modulator/ demodulator used as the backbone for a biphone carrier system is presented. Among its most specific features we mention its low power dissipation and few external components due to switched DC coupling, wide range and bias insensitive automatic gain control, very low carrier intermodulation.
