While LDMOS transistors aren’t exactly new – laterally-diffused MOSFETs have been appearing in RF power applications for decades – the particular parts used for the amp, NXP’s MRF300 power ...

It took a lot of tweaking — and a lot of MOSFETs — to get the candle to produce ... Note: [Jay] reached out to us after publication about mitigating RF noise. He does his experiments inside ...
