INTRODUCTION The RF6505 [1] integrates a complete solution in a single Front End Module (FEM) for WiFi and ZigBee applications in the 2.4GHz unlicensed ISM band. This FEM integrates the PA plus the harmonic filter in the transmit path and the LNA with Bypass mode in the receive side. It provides a single balanced TDD access for Rx and Tx paths along with two ports on the output for connecting a diversity solution or a test port. The CC2530 [2] is TI’s second generation ZigBee/IEEE 802.15.4 RF system-on-chip (SoC) for the 2.4GHz unlicensed ISM band. This chip enables industrial grade applications by offering state-of-the-art selectivity/co-existence, excellent link budget, and low voltage operation. The RF6505-CC2530 reference design [3] is a range extender design for the CC253x, CC2540-1 and CC85xx in the 2.4GHz ISM Bands. It increases the link budget by providing a power amplifier (PA) for increased output power, and a low-noise amplifier (LNA) with low noise figure for improved receiver sensitivity. In addition to these features it provides switches and integrated RF matching for design and high performance wireless systems. This reference manual outlines the expected performance when using a RF6505-CC2530 design under FCC Section 15.247 [4] in the 2400MHz to 2483.5MHz frequency band. This reference manual assumes the reader is familiar with the CC2530 and FCC 15.247 regulatory limits. For additional information or further questions please contact, RFMD Technical Support at [email protected]. Figure 1. RF6505CC2530 2. ABSOLUTE MAXIMUM RATINGS The absolute maximum ratings and operating conditions listed in the CC2530 datasheet and the RF6505 datasheet must be followed at all times.

SMARTRF STUDIO AND SMARTRF05EB The RF6505-CC2530 together with SmartRF™ Studio 7 software [6] and SmartRFEB can be used to evaluate performance and functionality. See Appendix for details on how to evaluate performance and functionality. The RF6505-CC2530 can be configured using the SmartRF Studio 7 software. The SmartRF Studio software is highly recommended for obtaining optimum register settings. 5. REFERENCE DESIGN CONSIDERATIONS The RF6505-CC2530 reference design includes schematic, gerber files and bill of materials. It is highly recommended to follow the reference design for optimum performance. Figure 4 shows the RF6505CC2530 schematic. 5.1 POWER DECOUPLING Proper power supply decoupling must be used for optimum performance. The capacitor C19 must be optimized to prevent RF leakage into the control lines of the RF6505 which may cause oscillations. 5.2 FILTERING The values of L5, L6, C11, C12, and C13 are for harmonics filtering purposes only. These components assist in the required filtering of harmonics to pass regulatory requirements. 5.3 PCB LAYOUT CONSIDERATIONS The top layer is used for components and signal routing, and the open areas are filled with metallization connected to ground using several vias. The areas under the two chips are used for grounding and must be well connected to the ground plane with multiple vias. Footprint recommendation for the RF6505 is given in the RF6505 datasheet. Layer two is a complete ground plane and is not used for any routing to ensure short return current paths. The low impedance of the ground plane prevents any unwanted signal coupling between any of the nodes that are decoupled to it. Layer three is a power plane. The power plane ensures low impedance traces at radio frequencies and prevents unwanted radiation from power traces. Layer four is used for routing. In layer, one open areas are filled with metallization connected to ground using several vias.

APPENDIX - PERFORMANCE VERIFICATION 8.1 EQUIPMENT 1. SmartRF Studio 7 installed on each PC used, which can be downloaded at SmartRF™ Studio 7 (SWRR085). 2. An RF generator with packet option, or a CC253x, or RF6505-CC2530 connected to a SmartRFEB for packet transmission. Using the CC253xEM or RF6505-CC2530 as an RF generator will require a PC. 3. A RF6505-CC2530 connected to a SmartRFEB and a PC for packet reception. 4. Attenuators and cable. 5. A 4.2V DC supply and a USB cable. 8.2 GENERAL SETUP 1. The firmware revision of the SmartRF Studio must be downloaded to the SmartRFEB. 2. Place the RF6505-CC2530 board onto the SmartRFEB via the evaluation module connectors. 3. Connect the USB cable from the PC to the SmartRFEB. NOTE: If the SmartRFEB is connected to a USB socket on a PC, it will draw power from the USB. The on board voltage regulator supplies 3.3V to the board, but has limited current source capability and cannot supply the RF6505-CC2530 with the optimum supply of 4.0V to 4.2V. An external supply is therefore needed and must be connected as shown in Figure 5. 4. Supply 4.2V DC to the SmartRFEB. 5. The chip type will appear in the test box labeled “List of Connected Devices” at the bottom of the SmartRF Studio Interface. This should read “USB device ID = 0xxx, Firmware (revision = 00xx), CC2530”. 6. Double click on the chip type in the device list to open up the SmartRF Studio7 device control panel for user interface. 7. Once the user interface is open find the “Range Extender” option, click on the arrow and select CC2591. Begin evaluating the RF6505-CC2530.

Complete steps 1 through 7 of the General Setup procedure. 2. Find the Continuous TX mode tab 3. Adjust your desired Tx power setting for CC253 using “TX Power” box in the RF Parameters section or by modifying the TXPOWER register value in the Register view. 4. Select the center frequency, either by using the “Frequency” box or using the “IEEE 802.15.4 channel” box. 5. Select between modulated and un-modulated in the Continuous T tab. 6. Select the correct antenna path, the two antenna paths are controlled thorough GPIO P1.0 and P1.1, so to change the antenna path from ANT1 to ANT2 the following registers needs to be changed; PODIR=0x82 and PO=0x7D, see Figure 6.

Packet TX Transmission Tab, ANT2 8.4 RECEPTION Practical Sensitivity testing To properly evaluate the receiver performance of the RF6505-CC2530 reference design, it is necessary to be able to find the sensitivity threshold, which is the lowest input signal the receiver can decode with acceptable signal quality. This reference manual describes how to test the sensitivity using a PER (Packet Error Rate) test. For questions on testing sensitivity with SmartRF Studio please refer to DN002 Practical Sensitivity Testing (SWRA097).

Packet Reception Tab PER Test Setup 1. Setup the equipment as shown in the block diagram in Figure 9. 2. Complete steps 1 through 7 of the General Setup procedure. 3. If using a CC2530 or the RF6505-CC2530 as the packet transmitter, use the Packet transmission section in this reference manual to setup the module that will transmit packets. Otherwise, setup the RF generator to send 802.15.4 packets and configure it for the selected RF frequency. 4. Select the Packet TX mode tab as shown in Figure 8. 5. Set the number of packets expected to receive. 6. Verify the antenna is correct on the interface and the base frequency matches the frequency of the board or RF generator that will be transmitting the packets. 7. Set attenuation level near the expected result. 8. Press Start to begin listening for packets before beginning to transmit packets. 9. Adjust the attenuation level until a 1% PER is achieved. 10. The Packet RX will continue until the number of packets programmed has been reached, or until 100 consecutive packets have been lost.
