TITLE:
Bi-Directional Amplifier System
Pins 12 and 13 are detector output voltages for the associated path. The DC voltage represents
the output power. These voltages can be used to roughly estimate the amount of output power.
For example, the donor antenna can be rotated to look for maximum output power if a spectrum
analyzer is not available.
Pin 14: Max sink = 1A.
14. Ground for Pins 10-13.
Pin 15: Max source = 80mA.
Pin 15: +5VDC, thermally fused (self resetting), 50mA max.
Pin 15 can be used as the drive voltage to disable the unit using Pin 9. It is also used to power
the performance monitor, when attached.
