Greetings fellow Repeater Builders and Communications
Aficionados,
As many of you know, Chip Angle (N6CA) of Angle Linear, a
luminary of the RF world, retired from his highly successful
business last year after a few years' consideration. For over
35 years, he hand-crafted some of the industry's most sought
after products that aid our communications systems in being
all they can be. Like a Swiss Clockmaker, he is a craftsman in
an arena requiring precision and quality. We all were sad to
see his great products become unobtanium, but we can all
appreciate an accomplished man wanting to close a chapter of
his life & enjoy the fruits of his labor.
Having known Chip a number of years now, and being aware of
his intent to retire, I'd reached out to him in a couple
discussions of the topic. I offered a true interest in
learning, continuing the essence of his products, and
hopefully enjoying similar success as he over time. We reached
agreement, and he gave me many helpful pointers to get
started. I am extremely thankful for his willingness to work
with me & his invaluable help. He is not only a skilled
craftsman, but a true gentleman. Again, a big thank you, Chip!
And so, the torch has been passed! As with any new venture,
there will be a process of ramping up. The intent is to offer
many of the same core elements formerly of Angle Linear, and
of like quality. Time will tell exactly the shape taken given
market demands, customer feedback, the ongoing learning
process, and evolving technologies in general.
Today, I am equipped to offer standard high quality PHEMT
preamplifiers. Under design are new High Level (High
Intercept) preamplifiers as well. Custom fabricated filters,
splitters and other accessories are not available today, but
are anticipated later. As a stepped process, the idea is
focusing on the essential items & graduate into greater
capability as time progresses. Eventually 'total-package' type
solutions would ideally be available such as drop-in
multicoupler systems or single system cavity-plus-amplifier
assemblies. Bear in mind, as opposed to more mass production
items, this remains a small-scale business producing
custom-to-order products. While standard guilelines of design
exist, each is tailored to the individual user's need within
practical limits.
The currently available PHEMT preamplifiers enjoy the same
operating specifications as their Angle Linear predecessors.
They are unconditionally stable, port matched, a +/-10%
optimized operational bandwidth, have moderate gain (12-22dB
dependent on band), and enjoy very low Noise Figure (.4dB
typical). The chassis is a rugged fully shielded cast aluminum
enclosure with connectors at its top, power supplied through
an RF-bypassing feed through capacitor & ground lug along
with transient suppression diode. Standard connectors are Type
N jacks. Other connector types available by special order
(BNC, TNC, SMA). Our preamplifiers can be cascaded with high-Q
filters/cavities without worry of oscillation or skewing
filter responses.
We are currently equipped to offer primarily UHF
(400-520MHz) band preamplifiers. Other bands will be available
as parts stock is accumulated. Standard pricing is $120 per
unit plus shipping, and turn-around is typically between 14
and 45 days depending on stock conditions. (Chassis and other
large parts are batch ordered and not quantity stocked at this
time)
Please contact us with your requirements. We look forward
to helping you optimize your communications system!
Regards,
Matt Lechliter
