Diy Ldmos Hf Amplifier

Diy Ldmos Hf Amplifier. VHF LDMOS Power Amplifier Experiments Baltic Lab Last measurement had P1dB around 580W at 50MHz, waveform & spectrum looked reasonably clean, gain still over 20dB Here's a site about building, testing, experimenting with LDMOS HF amplifiers

Author Topic: A 600W BROADBAND HF AMPLIFIER USING AFFORDABLE LDMOS DEVICES (Read 5105 times) ChrisSmolinski SMA connectors are rated for 600W continuous @ 1GHz, at HF they are limited by the insulation breakdown limit, which is typically around 300-350Vrms depending on who makes the connector
