HIGH POWER KLYSTRON GROUND TERMINALS
LD7111 SERIES
BAND, HIGH EFICIENCY, HIGH POWER GAIN
GENERAL DESCRIPTION
series LD7111 five-cavity Klystron Amplifier ideal earth-to-satellite communication systems. These designed operating over frequency range 17.3 18.4 GHz. instantaneous bandwidth minus one-decibel least over entire range. tubes forced-air-cooled power level. automatic channel tuner, which changes operating frequency very quickly simply, available series. Furthermore, they rugged reliable design offering long life service. LD7111 series compatible with VKU7791Z6 using additional adapter.

Note Absolute rating should exceeded under continuous transient conditions. single absolute rating limitation simultaneous operation more than absolute rating possible. Equipment design should limit voltage environmental variations that ratings will exceeded. Note Klystron body should ground potential operation. Note voltages referred cathode potential except heater voltage. Note optimum operating value shown test performance sheet each tube. Note Characteristics operating values this Data Sheet based performance test. These values changed result additional information product improvement. should consulted before using this information equipment design. This data sheet should referred contractual specification.
