TECHNICAL DESCRIPTION

Each amplifier is a PEP and average output power amplifier. The unit is enclosed in an EMI and RFI shielded, 19 inch wide rack mount chassis. Each unit can be stacked vertically without additional separation.

Each amplifier is designed for continuous transmit and uses forced air cooling by internal fans. The overall inlet to outlet air temperature rise is less than 14° C.

Each amplifier is powered from its internal power supply operating from a single phase 115AC power source. The maximum AC current consumptions is less than 570VA. Each unit provides the user with a "sleep" mode, so that if the unit sits idle, it will reduce its total power consumption to less than 80VA until the next time it is keyed.

Each amplifier uses a Y2K compliant, real-time micro controller to handle all system operation, protection, and management functions. The unit may be manually or remotely controlled using a four key, front panel keypad and display, or a rear panel serial remote communication port.

Each amplifier is designed around our standard 30 MHz - 400MHz, 100/200 watt, 27/30db gain, class AB amplifier module. Applied input power can be adjusted to accept from -20 dBm to +20 dBm, for use with a wide range of exciter products and installations. The overall gain of the power amplifier can also be adjusted in 0.5db steps through the front panel or remote interfaces.

Excellent harmonic performance is achieved by the use of a fast switching filter bank designed to operate in Frequency Hopping modes.

Each amplifier has Built-In-Test functions for easy troubleshooting. The unit is provided with VSWR protection, over-temperature protection, and amplifier system monitoring, to ensure reliable, long-term performance. The unit's Modular design provides a MTTR of less than 30 minutes.

The HPA100 & HPA200 also supports voice and data communications and is fully compatible with the requirements of MIL-STD-188-181, -182, and -183 DAMA, and 203-3 Link 4A.
