The paper presents the development results concerning a powerful (800 W) coherent pulsed transmitter of an upper-air radar system for atmosphere radio sounding with programmable tuning of the carrier frequency radio pulses in 1680 MHz range to provide a slant range measurement up to an upper-air radiosonde on the basis of a superregenerative transceiver (SRT). Field LDMOS transistors of 2П9110 type are combined into pallets to obtain high output power in amplification stages of the microwave transmitter. The results of measurements of microwave transmitter basic parameters are presented.
