    1.2 Purpose of Equipment The purpose of the LPA-9600 is to amplify the low level RF output of a separate exciter to produce 1.0 kW peak envelope power (PEP) or average power. The LPA-9600 is microprocessor controlled and operates in the frequency range of 1.6 to 30 MHz.
  • Page 20: Specifications

    The LPA-9600 is designed with an EMP environment in mind. All control and power lines into and out of the LPA-9600 are filtered. This filtering on the standard unit is adequate for a mild EMP. But for full EMP hardening, the optional EMP filter, which replaces the existing filter, is required. This filter is designed per approved EMP techniques and decouples every input and output line (except the antenna).

    Another non-resonant antenna is the longwire. The two most popular length longwire antennas are 75 and 150 feet. Both of these antennas require an antenna coupler to match the antenna to the LPA-9600. Figure 2.6-4 is an illustration of a 75-foot longwire installation. Note that the feed line from the antenna to the coupler is part of the antenna’s length.

  • Page 51 LPA-9600. A3A3U1 monitors the output of U9C and if it goes high for longer than 50 ms, then A3A3U1 causes the LPA-9600 to go to BYPASS by shutting down the power amplifier assemblies, preventing them from damaging the filter module.
  • Page 52 The purpose of the Reflected Fault Detector is to warn Microprocessor A3A3U1 when a severe reflected fault condition is occurring in the LPA-9600. If the reflected power level reaches and exceeds 200 watts, U9D goes high. A3A3U1 checks the reflected fault condition indicated by the Reflected Fault Detector to insure that it actually exists, and if so, immediately places the LPA-9600 in BYPASS.

    LPA-9600 T2 combines the two 100 ohm amplifier outputs into a single 50 ohm module output which delivers a nominal output power of 300 watts. This output combiner has properties similar to the input splitter. Each amplifier output is presented a load impedance of 100 ohms, regardless of the condition of the other output. In the event that one amplifier is delivering more output power than the other, half of the power imbalance is dissipated in the combiner dump resistor R40, and the other half appears as additional module output power.
