PPM transceiver SHF-module is designed for application in unidirectional rotating active phased arrays (APA) of the shipborne S-range radars with phase scanning. The module operates in transmit/receive mode. Phase control and power amplification of the probing pulses are performed in transmit mode. Preliminary amplification of the received signals with adjustable gain factor and phase control are performed in receive mode.
The function of continuous hardware monitoring for operability is realized in the module. Hardware monitoring means provide detection of the following failures:
<ul class="check"> <li>output signal exceeds power tolerance;</li> <li>temperature exceeds tolerance;</li> <li>VSWR-load exceeds tolerance;</li> <li>pulse duration exceeds maximum value.</li> </ul>
Output voltage of the module power supply to be enabled by +5 V voltage.
