3000 watts RMS amplifier for 1.8 to 30 MHz HF linear 50v LDMOS BLF188XR Ham
Contact info at the bottom. Proudly made in the USA with local, imported parts and original Ampleon transistors. I'm building dual or single LDMOS transistor amplifiers, also I'm building another LDMOS amplifier with 500 watts RMS. I can build any of them per your requirements.
I can sell you a power supply ready for the amplifier for an extra cost. 3000 watts RMS (or Average or Bird watts), 4000+ watts PEP, 4x BLF188XR, PTT input for TX, internal relay to turn off bias when stand by to reduce heating. 25 watts RMS minimum input (I can adjust this to any requirement, example 100, 25, 75 watts, etc) mono 1/4 jack for negative activation from radio or pedal. 2nd hand 50v only: includes 2 240v AC second hand power supplies(50v only) modified and ready to work with the amplifier, picture coming soon, very hard to get them for cheap.
Matching enclosure: I will build a 240v AC power supply in a enclosure that looks similar to the amplifier, includes all the voltages required for the amplifier, 50v and 12v. Requires 50 volts and 100 amperes power supply and 12 volts for bias, relays and fans. This is not a 12 volts amplifier. This sale is for the amplifier only, any other items on the pictures are not included. Amplifier approximate case measurements: 14 1/4" x 13 1/2" x 5 1/4 not counting the front switches, cables or back connectors.
All measurements are done using Bird 43 wattmeters, RMS readings are measured with dead key with the PEP kit turned off, PEP readings are measured modulated and the PEP kit turned on. We measured the harmonics using a Bird Signal Hawk spectrum analyzer. Other measurements are done with a Fluke scopemeter/oscilloscope.
All wattage measurements are off the air using a CDI 50 ohms 10kw terminating load (dummy load). Bird 43 measuring the output power, PEP kit off, 1x multiplier with a 5000 watts slug, 50 scale in the meter. Good ventilation, cool room temperature, 50 volts power supply with 100 amperes, ammeter and 12 volts power supply are required to operate this amplifier. You fail to do this, the amplifier dies, you decide. BLF188XR transistor is RUGGED, but that doesn't mean it will not fail, you can literally cut the antenna cable and it will not die, but you go more than 90 amperes (this amplifier with 4 BLF188XR), you will have shooting stars, please don't try cutting the antenna cable..... DO NOT OVERDRIVE THE AMPLIFIER. As a reminder, please don't overdrive the amplifier. Don't forget to use a Low Pass Filter on Ham radio bands, don't forget to NOT OVERDRIVE THE AMPLIFIER and the good ventilation with cool room temperature is very important, if you left your amplifier to melt itself like a Chernobyl reactor it's your fault, you been warned.
Please make sure you follow all FCC rules, this amplifier is not intended to be used on Citizen Band (CB), to be used without a low pass filter in the Ham bands(160-6 meters), to use it with more than 1500 watts in the HAM bands or to use it in digital mode. The power output of this amplifier will vary depending your radio, antenna, frequency, coax, SWR and any other circumstances. I will continue to improve the amplifier so maybe the pictures are outdated.
