  • Page 11: Chapter 1 Introduction

    Chapter 1 Introduction Bird 8860 Series Semiconductor Loads are portable 50 ohm coaxial RF transmission line terminations. They are designed for frequency ranges of DC – 28 MHz, specially calibrated for greater stability at 13.56 MHz. They provide accurate, dependable, and low reflection line terminations. Up to 1000 watts of RF power can be dissipated.

  • Page 12: Chapter 2 Theory Of Operation

    Theory of Operation Load Resistor Bird 8860 series loads consist of a thin-film-on-ceramic resistor immersed in a dielectric coolant. The resistor, individually selected for its accuracy, is enclosed in a special housing. When surrounded by the coolant, this produces a uniform, practically reflection-less line termination over the specified frequencies.

    If the shipping container is not damaged, unpack the unit. Save shipping materials for repackaging. 2. Inspect unit for visual signs of damage. Note: If there is damage, immediately notify the shipping carrier and Bird Technologies. Setting Up Note: Before first using the load, get a resistance baseline for future maintenance. Refer to "RF...

    Termaline® Semiconductor Load Resistor Installing the Thermoswitch Bird 8860 series loads can be equipped with an optional interlock thermoswitch, P/N 8890-008. It is normally closed, opening at 236 °C (457 °F), with a rating of 10A @ 120VAC and 5A @ 230VAC.

  • Page 15: Installing The Interlock Connection

    Installation Installing the Interlock Connection CAUTION If installed, connect optional interlock before applying RF power. 1. Unscrew the large knurled ring-nut (A) at the lower end of the coupling jack assembly. 2. Pull the large knurled ring-nut off the thermoswitch jack (B). 3.

  • Page 16: Connecting The Rf Power

    Termaline® Semiconductor Load Resistor Connecting the RF Power After installing the load, the RF transmission line can be attached using standard coaxial line coupling kits. WARNING Never attempt to connect or disconnect RF equipment from the transmission line while RF power is being applied. Leaking RF energy is a potential health hazard.

  • Page 17: Chapter 4 Operating Instructions

    Chapter 4 Operating Instructions Normal Operation Bird 8860 series loads have no indicators or operating controls. They require no special operating procedures or surveillance when their performance limits are not exceeded. Follow the instructions for the specific generator equipment. Operation Under Abnormal Conditions The load can be subjected to moderate overloads for short periods.

  • Page 18: Chapter 5 Maintenance

    Chapter 5 Maintenance WARNING Never attempt to connect or disconnect RF equipment from the transmission line while RF power is being applied. Leaking RF energy is a potential health hazard. WARNING Disconnect the unit from all power sources before servicing. The unit may be energized from multiple sources.

  • Page 19: Rf Assembly Resistance Test

    Maintenance RF Assembly Resistance Test Note: These tests are by no means a necessity to the operation of the load but merely guidelines for the users information. Accurate measurement of the DC resistance between the inner and outer conductors of the RF input connector will provide a good check of the condition of the load resistor.
