Functional Description / Operation of Modules (Draft)
EXHIBIT D1-6
There are three electrical connection assemblies on the PA:
• Power supply/communications connector (backplane connection)
• RF input/feedback connector (backplane connection)
• RF output connector (front “quick-N” or QN connection)
The PA is secured to the card cage with 2 TORX screws (T20 bit size required).
The PA has 3 front panel LED indicators that work in concert with each other. Their meaning is as follows when
the BR is powered:
1) PA TRANSMIT LED (Bi-Colored):
- RED LIGHT indicates that the PA is transmitting at less than full requested power
- GREEN LIGHT indicates that the PA is transmitting at full requested output power
- NO LIGHT indicates that the PA is not in a transmitting state
2) PA STATUS LED:
- GREEN LIGHT (on) indicates the PA is functioning normally
- GREEN LIGHT (off) indicates a PA failure
- GREEN LIGHT (blinking) the base radio is booting
3) PA ALARM LED:
- RED LIGHT (on) indicates a PA failure
- RED LIGHT (off) indicates that the PA is functioning normally
- RED LIGHT (blinking) the PA is impaired
The power amplifier (PA) module is a forced convection cooled RF power amplifier that operates to the following
