Accepts pulse from monostable mvbr and generates signal for sweep resolver of ppi radar. Voltage rises at constant rate during mono off time, and is held at zero during on time. Cascaded emitter-follower Q7-Q8 provides impedance match to output. Q9-Q10-Q11 provide required power for sweep resolver while preventing thermal runaway at normal temperatures.-C. E.
