Product reviews for 170-230MHz 400W Band III TV LDMOS 50V

My Solid-State Amp Project Single MRFX1K80H (1800watt CW @ 65vdc LDMOS) The Laterally Diffused MOSFET (LDMOS) is an asymmetric power MOSFET designed for low on-resistance and high blocking voltage. Originally designed by Motorolla, then renamed Freescale, then sold to NXP Observations: Keep your fans close to (on the fins of) the heatsink.
JUMA PA1000 is a ultra light weight only 5.5kg (12lbs) solid state 1kW linear amplifier for HF and 6 meter bands. It is especially very convenient for DXpeditions and similar traveling events as well as for station use.
The amp uses the NXP 1K50H LDMOS capable of over 1,500 watts, so you can run the amp at the recommended 1,000 output without driving the amplifier output beyond linearity. This is the same LDMOS used by SPE in their 1.3K-FA amplifier.
Setup procedure for a 2xblf188xr amplifier. A single device amplifier would be set for 2 amps. This amp was experimental.
Design of RF Integrated Circuit Power Amplifiers and Doherty Power Amplifiers, o 2-stage, 25W & 40W Si LDMOS RFIC PAs (0.7-1GHz), o 40W Asymmetric Doherty PA (30dB gain, 49% 2-stage PAE).

1KW LDMOS PALLET. 144MHz 2KW LDMOS all mode amplifier using 2 pcs BLF188XR. Both amplifiers are combined using Wilkinson couplers. The PCB of LDMOS pallet was orderd from Ebay and it is clone of W6PQL project. The price of LDMOS kit was 150$ (transistor not included), bought from "60dbmcom" Ukrainian seller: Ebay link. PCB matterial is ARLON TC-350, FR4 is not suitable for high power at 144MHz.
May 24, 2020 · Here's my latest dual 1K80H amplifier, mostly in pictures. Actually, this is not "my" design. I built this in an afternoon and it most resembles the Elecraft amplifier from the drains back (output section). The Elecraft output section design … [Continue reading] about January 2019 LDMOS Amplifier
