Abstract
This paper presents an experimental investigation on transmit pulse to pulse stability and receiver protection capability of a 1.4 kw s band transmit receive module (t/r module). Most modern radar transmitters require very stable inter and intra-pulse amplitude and phase performance. This is indeed a very challenging task due to maintaining electrical and thermal requirements in a very limited space. A compact high power t/r module is produced with a dedicated in-house waveform stability and surviving peak power test and measurement system. Lower than -60db of inter-pulse amplitude and phase stability figure is achieved at the transmitter. A peak power survivability test is also conducted at the receiver with 1.5kw and 500w peak power at duty cycles of %3 and %10, respectively. The module is exposed to operational burn in test in the lab for 12 hours and operational endurance test on the radar for 100 hours to validate its reliability.
