58 / 78 page  BLE CCxxxx WLAN CC3135 5 GHz SPDT RF SWITCH 5 GHz BPF 2.4 / 5 GHz Diplexer 2.4 GHz BPF A_TX A_RX SOP0 SOP1 RF_BG CC_COEX_SW_OUT CC_COEX_BLE_IN Coex IO RF Dual Band Ant. 1 Antenna Selection SPDT RF Switch Dual Band Ant. 2 ANT_SEL_1 ANT_SEL_2 BLE Ant. 58 CC3135 SWAS037 – JANUARY 2019 www.ti.com Submit Documentation Feedback Product Folder Links: CC3135 Applications, Implementation, and Layout Copyright © 2019, Texas Instruments Incorporated Figure 7-6 shows the antenna selection implementation for Wi-Fi®, with BLE operating on it's own antenna. The SOP lines control the 5 GHz switch. Note in this implementation no Coex switch is required and only a single GPIO from the BLE device to the CC3135 device is required. The Antenna switch is controlled by 2 GPIO lines from the CC3135 device. Figure 7-6. Coexistence Solution with Wi-Fi Antenna Selection and Dedicated BLE Antenna 7.1.3 Typical Application Figure 7-7 shows the schematic of the engine area for the CC3135 device in the wide-voltage mode of operation, with the corresponding bill of materials show in Table 7-1. Figure 7-8 provides the schematic for the RF implementation with and without BLE/2.4 GHz coexistence, with the corresponding bill of materials shown in Table 7-2.
