If it is a filter that we believe will eventually fit into our regular product line, we will ask you to purchase five and we will sell the other five. There will be no engineering fee. So if you round up some friends who want the same thing you want, it's pretty simple. We require payment in advance and our usual guarantee applies. If you want a filter that we do not believe will fit into our regular product line, you must buy ten.
Prices generally conform to our regular prices.
In either case, expect about ten weeks delivery for special orders. These filters have 50 ohm input and output impedances, and are designed to go in front of a receiver. They can be transmitted through at very low levels. Incident power levels must be held below 0 dBm to prevent crystal damage. These are 6-pole crystal filters.
