RF Crystals, Oscillators, Filters, Shields, and Capacitors

go right to the catalog! Skip the INTRO, Go RIGHT to the CATALOG!
These are the RF crystals, oscillators and filters we have in stock. Many unusual and high precision parts from top manufacturers like McCoy, Sawtek, Piezo Technology, Valpey-Fisher, Collins and others.

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 CLICKHERE.

Shipping*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.

We accept VISA/MC or international money order

* 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!
Don't forget these illustrated sections take a few seconds to load, but they are worth the wait!

Oven-Stabilized Crystal Oscillators
CTS, click to visit
Click to visit

CTS 03 OCXO Oscillator
16.384000.0 MHz OCXO
CTS 5VDC Oven stabilized Crystal Oscillators
Very nice sealed oscillators, run from existing +5VDC logic supplies (typ. 0.9A max current, 0.5A running), with excellent stability. Frequency is ideal for binary synthesizers, output is 1Vp-p clean sine wave on DC level (should be capacitor coupled to the next stage). CMOS internal design, with double walled thermal chamber. Frequency stability measured at better than +/- 0.5Hz after a 15 minute warm up, a very nice unit. Runs from +5VDC, for best stability, external power decoupling is recommended. Marked CTS-03, as well as 970-2129-0 and 214-1000-05. 2002 date codes, note that internal trimpot for frequency adjustment is accessible if hole at base is cleared of solder, just below +5VDC connection. Very handy to use an in inexpensive in-house check standard. A 0.5VDC drop in supply voltage (+4.5V) raised the frequency only 0.3Hz, an increase in voltage of 0.5VDC (+5.5V) lowered the voltage 0.3Hz. Ref. Voltage pin may be the fine trim, but was not tested, measures 0VDC. LOC: XTAL05/05A/WSS
