MKU PA 23CM-1000W CU, Power Amplifier

1280 ... 1300 MHz • 1000 W
Linear High Power Amplifier for the Amateur Radio Band 23 cm

High power, high efficiency and best linearity are achieved by our high power amplifier for the 23 cm amateur radio band. In comparison to tube power amplifiers, the used LDMOS transistors operate with a supply voltage of only +50 V DC. High voltage transformers, waiting for tube warm-up and retuning of the tube are the past! The amplifier can be mounted near the antenna to avoid power loss caused by long coaxial cable.
Safe operation is guaranteed by the internal overheat protection. The built-in sequencer can be used to control other devices like preamplifiers or coaxial relays. An output power of 2 kW is achieved by combining two MKU PA 23CM-1000W CU amplifiers. This is ideal for EME (earth-moon-earth operation)!

Please notice the following:
  • Attention: The recommended fans need a supply voltage of 24 ... 28 V DC.
  • The technical specifications refer to room temperature.
  • The power amplifier doesn’t contain any coaxial relays.
  • The recommended combination of heat sink and fan(s) is only specified for an ambient temperature of 25 °C.
  • Further information about dimensioning of heat sinks is available on our FAQ site.
  • We explicit point out that the recommended combination of heat sink and fan is not dimensioned for constant full output power of the power amplifier. The duty-cycle should not exceed 50% (1min transmitting / 1min receiving (WSJT)).
