1. [Amps] LDMOS HF amps (score: 1): Author: Don AD7LL <drfrasher@gmail.com>; Date: Sat, 8 Aug 2020 11:06:50 -0400; As my first retirement project I am hoping to build an LDMOS amp. I have made the decision to go with a single device, a BLF189XRBU. This is the same package as the more common BLF188, but rated at 1; /archives//html/Amps/2020-08/msg00032.html (8,746 bytes)

Re: [Amps] LDMOS HF amps (score: 1): Author: GEORGE WALLNER <aa7jv@atlanticbb.net>; Date: Mon, 10 Aug 2020 14:35:28 -0400; Don, I doubt that you will reliably get 1500 W out of a single BLF189 device. I have built three amps with single 188 pallets. With 49 V VDD they had outputs of 860 to 1140 W from 160 to 10 meters. (; /archives//html/Amps/2020-08/msg00040.html (10,494 bytes)
