English to Romanian Tech/Engineering Telecom(munications) Construction Information

Matched device pairs haven’t been used so separate gate bias is provided for each device, this bias is provided from a common source; ZD1 a 5.6 volt zener diode in series with D1 giving some temperature compensation. The driver transistors are running with a quiescent current set at 125mA each, gate load resistors R10 and R11 are ***** decoupled to ground via C9 and C10 *****so T2 “sees” a total load of 200 Ohms. The output load of Q2 and Q3 is provided by a centre-tapped transformer wound on a BN43-1502 or Epcos B62152A4X1 type core. As the two types have different AL values, different winding instructions are given for each.
