This is a primitive precursor, but basically just taking the power supply and magnetron out of a Microwave and feeding into a horn antenna. The focal point of a parabolic antenna will providing greater focus. This provides a kilowatt or so of RF but more intensity is desired. Moreover the AC power supply of microwaves can't easily be made as portable as one would desire. So instead a practical HERF gun would have a battery to power the magnetron filament, and then an inverter to charge some beefy photo flash capacitors to around 6kv, and then some means of discharging that into the magnetron such as a very high voltage triac or a tube called an ignitron, which is similar to a mecury rectifier tube with a grid which when biased negative prevents conduction but when positive bias applies, not only conductions but basically an avalanch break down occurs discharging the capacitors very rapidly through the magnetron.
An EMP gun is very similar in terms of power supply but instead of discharging into a magnetron you discharge it into a coil of very heavy gauge wire. This causes a very high magnetic field.
The method of destruction of these two devices is somewhat different, the HERF gun uses high power microwave to cause high power dissipation in the junctions of delicate semi-conductor devices turning them into slag, while the EMP tends to induce high voltages into delicate devices ruining them. Either can be effective at taking out an entire swarm of drones, but EMP is more difficult to shield against than microwave as the wavelengths involved will be much longer than the physical dimensions of the target.
It should be noted that high value capacitors charged to 6kv will kill you deader than a doornail if they discharge through your body in such a way as to pass through heart muscle and obviously the destruction of private property is obviously illegal. None the less, with this technology becoming common in war situations it is knowledge that is good to have.
