RF Diodes: Detectors, Mixers, PIN Diodes, Varactors and Varicaps Skip the INTRO, Go RIGHT to the CATALOG! These are the RF diodes we have, from microwave mixers and varactors to lower frequency varicap tuning diodes. Makers include Microwave Associates, MSC/Microwave Semiconductor Corporation, Motorola, and Siemens. Since many of these firms have stopped making these RF Power parts, are now gone, amalgamated, or regrouped, these can be a real life saver. We have sample tested each batch where possible, all parts tested were good. A huge range of parts, including many experimental parts and matched sets. We bought up several lab inventories (Including Rockwell/Collins surplus parts) and spares pools to get some specific parts we needed, and these parts are left over from those batches. Here's your chance to get some truly amazing parts at great prices. Quantities are limited, so when they are gone, that's it. NAVIGATION: To make your life easier, and help you find exactly what you want, we have broken the on-line equipment catalogs into smaller sections. Just CLICK on the item you are looking for at the left, to see the matching catalog. Large graphical catalogs are a bit SLOW, so please give them a bit of time to load. The top header of each catalog is largely the same, so don't think you are stuck in one place! You can order anything here just by picking up the phone, and calling (250) 769-1834 during normal office hours, 8:30AM to 4:30PM PST, or FAX to (250) 769-4106. OR, Email your order to Susan HERE. SHIPPING: Preferred and Alternate Methods as of June 4, 2013, CLICK for FULL DETAILS ON OUR FAQ Page. Rates are now changing rapidy, often with little notice to us, so all the data has been transferred to the FAQ page for speedy updating. E-Mail Susan if you want a quote for shipping to other destinations, or for something heavy. Sorry, we can't safely send most individual small parts in a regular letter envelope, they get destroyed by the automated handling equipment. Sometimes we can ship very rugged parts in a small padded envelope by letter post. Ask Susan. There is a packing charge for large or heavy equipment, see the FAQ for details. If we have your valid data on file, you can just click on the ORDER email link to place an order and indicate your approval to bill, and we will do the rest. We keep your active information for ONE YEAR for your convenience. If this is the first time you have dealt with us, you can phone +1 (250) 769-1834 or FAX +1 (250) 769-4106 to supply the billing info, or send it by the email link, as you prefer. We accept VISA/MC, international money order, Paypal (to Susan@Okanagan.net), and bank wire transfer. Please note that there are transaction fees with Paypal and wire transfer payments, the wire transfer fee is frankly horrifying. CONDITION: To answer your questions, YES, we completely check and inspect all used equipment, and do not offer any we feel is substandard. That gear is normally scrapped, broken down for parts, or may get offered as-is in the HOT DEALS section, with the unit's condition clearly identified. If there are any marks or detracting features, we clearly state them in the listing. Before shipment, we burn in the equipment for 24 hrs. again and re-check to be sure it is good prior to shipment. The CATALOG will appear below shortly!

ACRIAN MSC GHZ |
They closed in 1990, no good data sources have been found yet for those original parts, BUT, many seemingly identical devices were then made by GHZ Technology afterwards, when it absorbed Acrian. MSC (Microwave Semiconductor Corp.) appears to have become Acrian some time prior to the closure in 1990, probably in the early 1980's. GHZ is no longer active from what I can tell, but was the last incarnation of these compnaies. |
Alpha |
ALPHA Industries still exists, but it was merged with Connexant, and became SKYWORKS. Some original parts data still existis. |
Motorola |
Motorola seems to have jettisoned most of it's discretes business to On Semiconductor, but you can still find something here at the new incarnation FREESCALE. Many if not all RF devices are now moved to MA/COM according to Motorola's website. |
SGS-Thompson |
SGS-Thompson still has data for many of it's parts on line, some are dropped. Also good app. notes and other data. These pages move around on the site, so you may have to backtrack to find them if they get moved again. |
TRW |
TRW makes a lot of things, but it's hard to track down the data for semiconductor parts, they appear to be totally gone. |
MA/COM |
Good look up data for current products, but no obvious data for transferred Motorola parts. Microwave Associates was acquired by MA/COM, some parts still in production. It is now all lost within the labyrinth of Tyco, so finding things is getting very difficult! |
Philips |
Philips Semiconductor is no more, it has been spun off into NXP. Yet more confusion... |
Avago |
Most HP/Agilent RF semis now live at AVAGO. |
1N, 2N, MRF... PART NUMBER LOOK-UP |
Generic semiconductor part number look-up facility, works for ICs, Transistors, Diodes, RF parts, etc. Has MILLIONS of free data files, many impossible to find elsewhere. You will be amazed what you find there. |
