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. |
