70cm Projects - Amplifiers

100W UHF Linear Amplifier by M1GEO
his page details my building of Carlo Gnaccarini (VK3PY, formerly VK3BRZ)’s 100 Watt Power Amplifier for the 432 MHz Band based on two Motorola MRF646 transistors.

A 432MHz High Power Amplifier with a GS35b by DL4MEA
This amp is currently under construction. It does not work as expected, so here are just a few pictures from the construction. The cathode circuit is similar to CT1DMK's 70cm-GS35b.

A Dual­Band Power Amplifier by WN2A
It all started with a need to make my mobile FM setup more organized and less haywire. The end result is a neater solution with an auto band-switched unit that gives the amateur radio operator an indication of which band is being transmitted on.
