The purpose of the RF pager test jack is to min- imize the testing/troubleshooting and tuning times for pagers. Troubleshooting a pager which has mar- ginal page sensitivity normally requires the testing of several subsystems. Determination of an antenna problem or SOQ injection problem must be made. The unique design of the test jack and various plugs allow separation of antenna and RF input for accu- rate testing and tuning. Use of this test jack would eliminate the need for having to desolder isolation components and solder test cables. Figure 1 shows three spring steel contacts and what the basic jack design would look like. The jack design separates the antenna from the RF amp with plug insertion while providing a ground reference and capacitive tuning. The plug design has three separate contact areas; the tip for RF injection, the middle for ground, and the area furthest from the tip for the antenna response.
