G.T. Microwave Inc. part numbers are composed by selecting the codes for TYPE and MODEL, then calculating CENTER FREQUENCY and BANDWIDTH to obtain the codes, selecting the code for temperature ronge and finally selecting the code for SWITCHING SPEED. If required, the factory may assign a Unique model identifier. Use the examples to the right or consult a factory
representative.
