3.5mm 10MHz-26.5GHz Directional Couplers Here is a great opportunity to buy a pair of high quality microwave couplers. You can even use these as a basis for a network analyzer! These couplers are in good working order and have been individually tested. Data can be provided if desired but, because of normal measurement uncertainties, the actual numbers cannot be exactly specified or guaranteed. These couplers have been salvaged from instruments and all are roughly 7 years old. Functionality is guaranteed (see below.) While the couplers are only specified from 10 MHz to 26.5 GHz, they seem to work reasonably well down to about 3 MHz (tested) and probably up to 33GHz (not tested; just a guess.) About these couplers These are nominal 16dB couplers. They have 3.5mm connectors on all 3 ports. Insertion loss is about 1.5dB at the low end, rising to about 3dB at the high end. Typical directivity and port match are both about 20dB over most of its range. The physical size, exclusive of connectors and screw heads, is about .55 x .9 x 1.7 inches. Each one weighs 1.5 oz. There are two "through holes" that can be used for mounting purposes. I can provide some actual measured electrical data for each unit if needed. Each unit will also be tested to assure mechanical and electrical stability. Other specs: Max power to test or input port: 1.5 watts Max DC to test or input port: 24 Volts Operating range: 0-70 deg. C This auction is for a pair of these couplers as show in the picture (ruler not included!) The other pictures show a representative sample of insertion loss, coupling factor, directivity, and port match. Since I have several of these, the unit you get will probably differ from the sample. If you only need one coupler, let me know. I have several pairs available. Payment and Shipping Details Buyer will have 15 days to verify full functionality. If anything is found to be defective (unlikely), I will substitute another unit. Any refund will exclude shipping charges. I will only ship to addresses within the US, so don't ask. Shipping charges are fixed at $10 for USPS Priority mail. Faster shipment methods can be requested but will result in a slightly higher charge. Let me know if you have any questions.
