Large power RF Power Amplifier

To obtain a large RF power taken in the usual way to do that is installing the components to be duplicated into two four or even more to put together the output to produce the output power is doubled. There are several ways in which that is; Pushpull, combiner, and Balance. The first experience when beginning to try to double, I use became an increasing power transistor 2SC1970 doubled, definitely glad that successfully and naturally obsessed to try a more challenging again. The Homebrew too so yes! to not care about spending their money that important work. It is remarkable that a firm commitment, and that's what makes us succeed.

Figure 1. 150 Watt RF Power

Transistors are commonly used to build this project can be 2SC2782, or 2SC2094, or 2SC2630. Keep in mind that in building the RF power in this way to be able to exit the output as expected, it is necessary also to consider in the input. So here, for a 2SC2782 RF power will be able to power out 80 Watts using 2SC1946 power driver. Now we expect in the way in Pushpull, Combine, or Balance, RF power can go out as much power two 160 Watt. Was only able to drive with a 2 X 2SC1946 2SC2782 get out to achieve the power of 160 Watts? Could be less. Ideally also need 2 x 2SC1946. Yes it is enough for 2SC1946 because it was able to enlarge the output power to almost two folding, but 2SC1946 pity works because it has to be pumped all-out to maximum, He also still use. That sounds good if you want to try a power driver 2SC2630 even though it is not practical. Wow steady results! Ko-Ko Full Power. 2SC2630 issued its relaxed as small as needed, then simply driven with 2SC1947, and the output is pumped into 2 x 2SC2782A
