USED ASTECH RFPP ATL-100RA Impedance RF Auto Matching Network

ASTECH RFPP ATL-100RA

The ASTECH RFPP ATL-100RA matching network is supplied with a built-in controller. This matching network is provided with status indicators on the front panel and analog remote signals necessary for system control but does not have manual control switches and tune/load position indicators.

  • Fast Initial Matching: about 2 seconds
  • Fast Continuous Matching: instantaneous
  • Precise Resolution: about 1% or less reflected power
  • Auto Preset

Model Frequency Power Resistance Cooling Dimensions
ATL-100RA/DT2 400 kHz 1 kW 50 Ohms Air 8 x 18 x 8"
ATL-100RA 350 kHz .500 kW 50 Ohms Air 8 x 18 x 8"

The matching network uses a pulsed voltage servo motor driving circuit, which supplies pulsed voltages to the servo motor. The pulse width is controlled by the TUNE or LOAD error signals. This provides extremely high speed matching with precise resolution. The life of the servo motor is enhanced since there is a constant voltage supplied to the motors. The unit also uses brake circuitry, which brakes the servo motor when TUNE or LOAD is just passing the matching position. This feature prevents oscillation of the TUNE and LOAD motors and stops them at the matching position. The matching network incorporates an extremely precise sensor circuitry which is controlled by the RF power level. This enables the unit to operate with high resolution over a wider dynamic range of RF power. The unit will automatically preset the TUNE and LOAD positions by detecting AC power on, RF Power off, or TUNE and LOAD, reaching thee limits at the same time. This results in hands off operation. This function can be disabled by simply changing jumper plugs. TUNE and LOAD position meters are available, which permits easy reading of positions without opening the unit. LEDs are used to indicate phase (lead/lag) and magnitude (high/low). Should the network be unable to find a match point, these LEDs will remain lit. This gives the operator visual indications of the matching condition. LEDs are also provided for TUNE and LOAD limits.
