Descripción
The present article shows the design of a transmitter with an output power of 400 watts for the MIDS Communication System (Multifunctional Information Distribution System), using LDMOS technology. This NATO communication system requires to use of equivalent pulse widths of 3 milliseconds with 20% duty cycles in a frequency band between 950 and 1215 MHz (30% of relative bandwidth), operational features much more restrictive than primary and secondary radars ones. This prototype is a previous work for a complete future amplifier scheme with more than 1Kwatt output power, combining 8 LDMOS amplifiers and only two amplifying stages, allowing and overall power gain of more than 20 dB, which is not possible with bipolar transistors. The purpose of this system is to locate them in military vessels, where a large coverage and a high countermeasures level are required. This kind of transmitters is usually called in the MIDS system High Power Amplifier Group (HPAG).
