1kW 1.830MHz, 700W 50MHz HF POWER AMPLIFIER BOARD for LDMOS BLF188XR/XRS, BLF188

Diy Ldmos Hf Amplifier. 500W Mrf300 LDMOS 144148MHz RF linear amplifier diy kit ( NO MOS tube) FOR Ham Radio Amplifiers I purchased most [1] of the boards in kit form, rather than pre-Figure 2 — Amplifier rear panel Here's a site about building, testing, experimenting with LDMOS HF amplifiers

So after the release of the new LDMOS devices which seemed to be more robust i decided to start another project with the BLF188XR ldmos I purchased most [1] of the boards in kit form, rather than pre-Figure 2 — Amplifier rear panel

I have reworked the output a bit since the article, lost some efficiency and P1dB at 1.8MHz and harmonics look worse now (LPF will solve that) but 3.5 and 7MHz are better and 50MHz is better as well; I expect it to be usable on 70MHz too now. Linear amplifier kits and filters available in the shop.
