Summary of Contents for Tokyo Hy-Power HL-1.1KFX

  • Page 1 Users Manual Solid-State HF Band 600W Linear Power Amplifier Model HL-1.1K...
  • Page 2 Introduction Thank you for purchasing the HL-1.1K This compact and lightweight desktop HF linear power amplifier has a maximum input power of 1.35kW. Our solid-state broadband power amp technology makes it the smallest and lightest in the industry in its class. Typical output power is 600W PEP (SSB, CW) with the drive power of 65-90W.
  • Page 3 The amplifier has fast acting sophisticated protection circuits. Please note, however, any such actions that cause the same fault to occur repeatedly, will lead to failure of the valuable final power FET transistors. Before checking inside the amplifier, be sure to wait a few minutes for the high DC voltage to discharge (monitor Vd meter reading).
  • Page 4 Features Our solid-state broadband design engineers worked to make the HL-1.1KFX, the lightest and most compact 600W out portable HF amplifier in the industry. This world-class compact 600W HF amplifier is the easiest to handle and operate anywhere in the world.

  • Page 12 Turn the POWER switch on. Turn the BAND switch to a desired operating frequency band. Turn the STAND-BY switch to OPER (operate) position and the amplifier is ready to go. If you key the transceiver with the carrier level set relatively low (such as 20-30W), you will achieve an amplified output signal of few hundred watts.
  • Page 13 ALC Connection ALC voltage is available at the terminal marked ALC (RCA phono jack) on the right upper corner of the rear panel. Negative maximum DC voltage of ten volts (-10V) is produced at this terminal when the amplifier is fully driven. This voltage is adjustable with the ALC ADJ.

    Protection Circuits There are five major protection functions in this amplifier. If the amplifier has shu down for some reason, before re-setting, correct the possible cause of the shut down. Turn off the POWER once and back on to reset. O.

Explanation of Major Circuits Five major circuit blocks are explained in their basic form and using signal flows. 10-1 Main DC Power Supply 10-2 Power Amp/ L.P.F. 10-3 RF Power Detector/ TX-RX Switching 10-4 Control Board 10-1 Main DC Power Supply The main DC power supply feeds the 50V DC power to the final PA stage.
  • Page 16 10-4 Control Board (PC1698) This is the heart of the control signal processing for the HL-1.1KFX. It judges the operating condition of the amplifier, as well as issuing the commands to the peripheral circuits. Various analog signals are processed such as RF drive from the transceiver, RF power signals at various points, DC power supply information, etc.
