摘要:The modulator system comprises emitter follower type first and secondtransistor pairs with their emitter electrodes commonly connected, and an emitterfollower type third transistor pair with their emitter electrodes commonly connected.Clamped modulation signals having opposite polarities are supplied to the base
electrodes of the first transistors of the first and second transistor pairs, whereas signalsto be modulated and having opposite polarities are supplied to the base electrodes ofthe second transistors of the first and second transistor pairs. The base electrodes of thefirst and second transistors of the third transistor pair are connected to the commonlyconnected emitter electrodes of the first and second transistor pairs, thereby producinga modulated output signal from the commonly connected emitter electrodes of thethird transistor pair.
