Figure 3 shows the positive and negative limiter circuit with the same relative proportion of high-power amplifier. Positive and negative limiter circuit consists of diodes D1, D2 to achieve, plus the forward voltage across the diode, the diode conduction, that is, when T DA2030A output voltage is h

Figure 3 is a plus or minus band circuit 50-200 compared with example amplifier circuits. -17.6 limit circuit from 2 diodes are D D , 1, 2 to 2 diodes are two ends, 2 plus the forward voltage diodes are misleading links, i.e. when T DA A 2030 the output voltage is higher than 15 V D T DA 2030 2impor

Figure 3 has the positive and negative limiter circuit high efficiency synchronism proportion enlargement electric circuit.The positive and negative limiter circuit by diode D1, the D2 realization, when the diode both sides add the direct voltage, diode breakover, namely when the T DA2030A output vo

Figure 3 high-power in-phase with a positive and negative limiting circuit amplifier. Positive and negative limiting circuit is realized through diode D1, D2, diode Jiazheng at both ends to the voltage, the diode conduction, t-DA2030A that is, when the output voltage is higher than 15 v, the D2 on-,

Figure 3 shows the positive and negative limiter circuit with the same relative proportion of high-power amplifier. Positive and negative limiter circuit consists of diodes D1, D2 to achieve, plus the forward voltage across the diode, the diode conduction, that is, when T DA2030A output voltage is h
