    Overview Power Supply The BLE100 power supply is a separate circuit board mounted to the underside of the amplifier module and is capable of 60 VAC or 90 VAC powering. The power supply provides a regulated 24 VDC output over an AC input between 38 Vrms and 90 Vrms with a line frequency from 50 Hz through 60 Hz.
  • Page 18: Forward Path

    Forward Path The operational gain of the BLE100 amplifiers is 34 dB with 16 dB of return loss. The operating gain includes provisions for the insertion loss of the input cable equalizer and required reserve gain to operate the Bode equalizer in the middle of its range. The low-noise figure, pre-amplifier stage, is a 1 GHz hybrid followed by a power-doubled output stage.

    A 20-ampere, blade-type fuse is furnished in the amplifier module and provides overcurrent protection for AC power applied to the input. You can power the BLE100 from the output without passing power through to the input port. To block power from the input port, remove the power-block jumper illustrated in Figure 2-8.
  • Page 36: Bench Testing

    The following subsections provide instructions to bench align the BLE100. Before You Begin The BLE100 is shipped with a 20 ampere blade-type fuse in the output port for over current protection. CAUTION! To avoid applying 60/90 Vac to the test equipment during testing, remove the fuse illustrated in Figure 2-8.
  • Page 37: Test Equipment And Connections

    Bench Testing Test Equipment and Connections The equipment typically used for testing the BLE100 consists of a network analyzer such as the HP 8712 or 8713 series, a 60/90 Vac bench power supply, a cable simulator, a Motorola model SSP-PIN power combiner, and a variety of jumper cables, adapters, and fittings.
  • Page 38: Example

    The result must meet advertised specifications for the unit. The operational gain of the BLE100 provides reduced gain capability. This enables the unit to operate in the proper region of the Bode board when it is controlled by the ADU/QADU or TDU drive units.
  • Page 39: Testing Return Gain And Response

    Reconnect the test equipment and switch the sweep input and sweep output leads of the BLE100 under test to be opposite of the connection shown in Figure 4-1. Remove the power block at the input port and replace the 20 A fuse at the output port (both illustrated in Figure 2-8) before you apply power.
  • Page 40: Installation

    Although it is desirable to have a full complement of channels available for balancing, you can adjust the BLE100 adequately with a limited number of channels. You can install the BLE-HSG/15 on a messenger strand (aerial) or in a pedestal. The following subsections provide details on each application.
