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.
