00:00Hunting high-power RF silicon. Today TestBench decides,
00:04original MRF 392 style builds versus MRF 9120 LDMOS.
00:09Found best supply deals on top choices online.
00:13First up, classic Motorola MRF 455. Proven bipolar workhorse for HF rigs up to 30 MHz.
00:21Push a solid 60W output with high gain. Runs $28.01 massive 4,000 plus units sold
00:29with 4.6 star rating. Pick this for bulletproof vintage HF amplifier repairs.
00:35Next, budget MRF 9120 single-piece encase 375B04 packaging.
00:42Real end-channel lateral MOSFET architecture. Built for linear power-up past 900 MHz with
00:48way better efficiency than older bipolar parts. Costs $16.44. 2400 sold, 4.7 stars.
00:59Best bargain entry into modern VHF slash UHF builds.
01:03Third, bulk pack 2N5485 CHFETs, 100 pieces total. 292 footprint for VHF front ends,
01:11mixers, low-noise preamps. Not final stage power, but need clean input signal before
01:17feeding hungry finals. $31.93 for entire lot. Over 2300 sold at 4.5 stars. Essential bench stock
01:28for dirt-cheap RF front-end stages. Fourth, Motorola MRF 184 broadband lateral MOSFET.
01:35Rated 28 volts, 60 watts, flat response up to 1 GHz encase 360B01. Insane linearity across wide
01:44bands without thermal runaway risks of old bipolars. Costs $15.06. Sold over 2,000 times
01:52with 4.6 rating. Grab this for wideband VHF slash UHF experiments on budget.
01:59Fifth, guaranteed brand new MRF 9120 factory fresh unit. Serious lateral MOSFET pushing full 120 watts at
02:07880 MHz on 26-volt rail. Hits peak thermal efficiency and maximum output specs without
02:14clone lottery risk. Price jumps to $53.39. 1400 sold, solid 4.6 rating. Buy when project demands
02:25maximum clean wattage and zero failure risk. Links to every RF transistor in description below.
