There should not be top copper layer near the test pin area shown in Figure 1-7. When laying out the host PCB, the areas under the antenna should not contain any top, inner layer, or bottom copper as shown in Figure 1-8. A low-impedance ground plane will ensure best radio performance (best range, lowest noise). Figure 1-8 shows a minimum ground plane area to the left and right of the module for best antenna performance. The ground plane can be extended beyond the minimum recommended as need for host PCB EMC noise reduction. For best range performance, keep all external metal away from the ceramic chip antenna at least 30 mm. BM70BLE01FC2 The BM70BLE01FC2 physical dimensions are shown in Figure 1-9, recommended host PCB footprint in Figure 1-10, and mounting suggestion in Figure 1-11. It is highly recommended to layout the host PCB as suggested in Figure 1-11. A low-impedance ground plane will ensure best radio performance (best range, lowest noise). Pin 30 (BT_RF) is a 50 ohm connection to an external antenna connector, PCB trace antenna, or component (ceramic chip) antenna through a host PCB 50 ohm micro-strip trace. This trace can be extended to include passive parts for antenna attenuation padding, impedance matching, or to provide test posts. It is recommended that the micro-strip trace be as short as possible for minimum loss and best impedance matching. If the micro-strip trace is longer, it should be a 50 ohm impedance. Figure 1-11 shows an example connection to U.FL connector. 2015 Microchip Technology Inc.
