\nthis bias circuit by DB6NT is used (slightly modified)..<\/p>\n<\/a><\/p>\n
10 GHz – 1Watt PA, made from 14 GHz surplus stuff<\/p>\n
# use 0805 or 1206 capacitors with low values (10pF or less) with white ceramic (NPO material , low RF losses)
\n# capacitors are glued with “Velpon” ( a Dutch brand) glue, don’t use cyanoacrilate like “one second glue”
\n# tune for minimum smoke and maximum power with a wooden stick, use eventually a ceramic trimming stick for
\ndetermining the spots where a capacitor can be placed. ( fast scan for sensitive places)
\n# a spectrum analyser for this tuning is preferred above a wideband power meter, oscillations can be seen on a analyser
\nI used a HP141T with 18 GHz plugin and a hp8620 sweeper with 8-12 GHz plugin as signal source<\/p>\n
