GEN 4 MAGNETRONS
One of our key products are the new GEN4 magnetrons. They are available in 4, 6 and 12.5kW and designed to meet new IMO requirements on spurious frequencies. GEN4 offers the latest magnetron technology, not only to service new radars, but also to service older equipment.
One model fits all
The new GEN4 magnetron can be installed in almost any radar using the same kW output because of its compact design.
If the footprint is different, you can use the simple adapter plate. The magnetron is so light that it can be fitted directly on the circulator without additional support.
Example: MG5248 = MG4004 + Adapter plate A
Adapter baseplates
Many types of radar are fitted with magnetrons that have a GEN 2 style base plate size (113mm). This is the same size as popular GEN 3 magnetrons, such as MG5241 and MG5424.
We have developed two adapter plates, model A of 113mm and model B of 135mm, to fit the new GEN 4 4-, 6- and 12.5kW magnetrons in the space that takes 113mm long magnetrons.
These plates are standard packed with a set of 10mm M4 screws and washers to fit the GEN 4 magnetron on the adapter plate and a set of maintenance screws in a variety of lengths, to ensure that you always have the right screws for installation. With these plates you can fit a new GEN 4 magnetron in any 4-, 6- and 12.5kW radar.
Many radar manufacturers already use the standard screw hole configuration to fit the compact and 113mm length magnetrons. The new 12.5kW magnetron will fit into Furuno models that take a 9M602 and MG5241.
Advantages of GEN 4
Some of the advantages of the GEN4 magnetrons are:
- Fully compatible with GEN 2 and GEN 3 magnetrons.
- Smaller outline than the outline of GEN 2 and GEN 3 magnetrons, avoiding replacements that do not fit.
- Better performance when compared to the original GEN 3 magnetron.
- Replaces almost any other magnetron with the same output, using adapter plate A or B.
- No need to keep a wide range of models in stock, because one of each 4-, 6- or 12.5kW model can service almost every 4-, 6- or 12.5kW radar.
Spurious emissions
The main reason for the development of the new generation was to design a magnetron that meets the new ITU bandwidth limits. EEV succeeded; the new GEN 4 magnetrons meet the new regulation without additional band pass filters.
The design of the modulator, however, is just as important, as it drives the magnetron. A poorly designed modulator can cause even the best magnetrons to generate out of the band pulses. Results in the field and test laboratory confirm a very good performance from GEN 4 magnetrons in radars originally fitted with GEN 2 or GEN 3 magnetrons.
