It's built for the HF-to-VHF band — think broadcast transmitters, ISM generators, and amateur radio power amplifiers. The 21.1 dB gain at 100 mA test current means a modest driver stage can push it to full output. The 133 V drain rating gives headroom for 50 V supply designs. ## Package and mounting It comes in a TO-220-3 package. The tab is the drain. ## Lifecycle and sourcing reality This part is listed as Active and ROHS3 compliant. No end-of-life notice, no last-time-buy clock ticking.","metaTitle":"MRF101BN RF MOSFET LDMOS, 115W, 1.8-250 MHz, TO-220-3","metaDescription":"NXP MRF101BN LDMOS RF power transistor, 115W output, 21.1dB gain, 1.8-250 MHz.
