OPERATING INSTRUCTIONS
NTHX51AA
Note: These operating instructions describe the procedure for turning on and off the amplifier
output power using signal generators. This amplifier will be used with transmitters which have been
or will be type accepted separately. The specific transmitter instruction book should be consulted for
the correct method to use this amplifier with transmitters.
1.
The input voltage range, applied to pin A2 of the connector, should be between 20.95 and 29.5 VDC.
Pin A3 should be grounded.
2.
A CMOS-level pulse (Vh > 3.5 VDC, Vl < 0.5 VDC) of frequency greater than 1 Hz must be applied to
pin 5 (chip select input) of the connector. This prevents the watchdog timer circuitry from disabling
the RF circuitry of the amplifier.
3.
Pin 3 of the connector functions as the PA Enable. A CMOS high applied to Pin 3 enables the RF
amplifier. CMOS low disables the amplifier.
4.
The RF input is Pin A4. The output is Pin A1.
5.
Pins 10, 15, and 17 should be connected to ground
6.
To turn on the amplifier, first apply the DC voltage within the range specified above (25.15 VDC
nominal.
7.
Turn on the pulse to the chip select line (Pin 5).
8.
Turn on the PA Enable (Pin 3).
9.
For full rated output power (+47.5 dBm), the gain range may be from 23.5 to 27.0 dB. Increase the
input power to the amplifier until the desired output power, monitored at the output connector, is
reached.
10. The gain may change up to 0.5 dB as the amplifier temperature stabilizes after turn-on. Let the
amplifier warm up for 10-30 minutes, then re-adjust the power to compensate for the gain change.
11. The amplifier is now operational.
12. Additional functions are available through the digital control circuitry. They are not necessary for
turning on the amplifier and obtaining the desired signal, but they do communicate information to the
Transmit/Receive Unit (TRU). Since these functions are controlled by the TRU, instructions for using
these functions are contained in the specific TRU manuals, not the amplifier manual.
a.
Pins 8 and 9 are serial data lines accessing the EEPROM and digital control circuit.
b.
Pin 4 is used for the system clock. The TRU will provide a 24.3 kbits/s signal when performing
an EEPROM read, and 9.72 kHz when clocking in the address and clocking out the data for A/D
operations.
c.
Pin 6 is a CMOS input for selecting either the A/D converter or the EEPROM for the desired
communications.
d.
Pin 11 is connected to the alarm LED anode. The TRU determines whether an alarm condition
exists.
e.
Pin 12 is connected to the alarm LED cathode.
f.
Pin 13 is used for EEPROM register protection.
g.
Pins 14 and 16 are not used.
