Just came across this news release this morning.
I have 2 very well known tube amps and built a W6PQL SSPA with a pair of
BLF188XR devices after one of the tube amps failed. The home-built
solid-state amp is a keeper and I am seriously looking to parting ways with
my tube amps. Instant on, no lethal HV, tons of gain (minimal drive
requirements) are all significant benefits. A BLF188XR is $185 from RF
Parts.
The SS amp has been running very nicely now for the past 5 months. Only for
RTTY contesting have I needed to revert to a tube amp.
So long as the NXP/Freescale/Ampleon conglomerate pushes the RF envelope
with their LDMOS transistors, we in the amateur community will stand to
benefit. SSPA designs will continue to improve to silence the naysayers.
I did not include the direct link due to security/SPAM concerns.
Just search BLF189XR. Most of the search results will take you to the
Ampleon Press Release.
73 to all--
Mark
