3 RF Exposure conditions 3.1 Installation Instructions The module is approved for use in a mobile RF exposure environment. A minimum separation distance of 20 cm must be maintained between the antenna and nearby persons. The module is not approved for co-location with any other modules. 3.2 Warning A warning must be placed in the host product user instructions stating that: 1) “This device is approved for use in a mobile rf exposure environment.
For information describing how to properly design circuits compliant with these requirements, see Antenna interfaces. 4.2 Approved antenna designs JODY-W2 modules come with a pre-certified design that can be used to save costs and time during the certification process. To minimize this effort, the customer is required to implement antenna layout according to u-blox antenna reference designs. Reference design source files can be provided on request by u-blox.
4.3 Other remarks 4.3.1 Unused pins ☞ JODY-W2 modules have pins that are reserved for future use (NC). These pins must be left unconnected on the application board. 4.3.2 GPIO usage ☞ The reconfiguration of signals marked as GPIOs on the JODY-W2 module for applications not listed in this document depends on the respective firmware release. 5 Design-in 5.
Accurate design is required to ensure proper functionality. Follow the General highspeed layout guidelines and recommendations for the High-speed UART interface. 5.2 Antenna Interfaces JODY-W2 modules provide the following two RF interfaces for connecting the external antennas: • • The ANT0 port for Bluetooth connectivity. The ANT1 port for Wi-Fi connectivity.
Figure 1: Transmission line trace design To properly design a 50 Ω transmission line, the following remarks should be considered: • • • The designer should provide enough clearance from surrounding traces and ground in the same layer; in general, a trace to ground clearance of at least two times the trace width should be considered, and the transmission line should be “guarded” by ground plane area on each side.
• • • • • • For PCBs using components larger than 0402 and dielectric thickness below 200 µm, it is recommended to add a keep-out (that is, clearance, a void area) on the ground reference layer below any pin present on the RF transmission lines to reduce parasitic capacitance to ground. The transmission lines width and spacing to GND must be uniform and routed as smoothly as possible: route RF lines in 45° angle. Add GND stitching vias around transmission lines as shown in Figure 2.
5.2.2 Antenna Design Designers must take care of the antennas from all perspective at the very start of the design phase when the physical dimensions of the application board are under analysis/decision, since the RF compliance of the device integrating JODY-W2 module with all the applicable required certification schemes heavily depends on antennas radiating performance.
A numerical example for estimating the physical restrictions on a PCB is given here: Frequency = 2.4 GHz → Wavelength = 12.5 cm → Quarter wavelength = 3.5 cm o Radiation performance depends on the whole product and antenna system design, including product mechanical design and usage. Antennas should be selected with optimal radiating performance in the operating bands according to the mechanical specifications of the PCB and the whole product.
Item Isolation (in-band) Requirements S21 > 30 dB recommended Isolation (out-of-band) S21 > 35 dB recommended S21 > 30 dB acceptable Remarks The antenna-to-antenna isolation is the S21 parameter between the two antennas in the band of operation. Lower isolation might be acceptable depending on use-case scenario and performance requirements.

IPX ultra micro-miniature RF connector Table 9: U.FL compatible plug connector Remarks Recommended Typically, the RF plug is available as a cable assembly. Different types of cable assembly are available; the user should select the cable assembly best suited to the application.
5.2.2.2 Integrated Antenna Design If integrated antennas are used, the transmission line is terminated by the antennas themselves. Follow the guidelines mentioned below: • • • • • • The antenna design process should start together with the mechanical design of the product. PCB mock-ups are useful in estimating overall efficiency and radiation path of the intended design during early development stages. Use antennas designed by an antenna manufacturer providing the best possible return loss (or VSWR).
This document supports a connector-based design for the use of external antennas (one for each antenna pin of the module). 6.2 General description and requirements JODY-W2 series modules provide two RF interfaces for connecting external antennas. The antenna ports ANT0 and ANT1 have a nominal characteristic impedance of 50 Ω and must be connected to the related antenna through a 50 Ω transmission line to allow proper impedance matching along the RF path.
Item Isolation (in-band) Remarks The antenna to antenna isolation is the S21 parameter between the two antennas in the band of operation. Isolation S21 > 35 dB recommended Out-of-band isolation is evaluated (out-of-band) S21 > 30 dB acceptable in the band of the aggressor to ensure that the transmitting signal from the other radio is sufficiently attenuated by the receiving antenna to avoid saturation and intermodulation effect at the receiver’s port. Envelope correlation ECC < 0.
Figure 4: Test set-up 3.1 RF trace PCB routing The PCB routing connecting the module’s antenna pins to module board U.FL connectors are designed with coplanar microstrips. Coplanar microstrips are also used on the carrier board connecting the U.FL connectors with the SMA connectors to which the external antennas or test equipment are connected. Figure 5 and Table 12 shows the design stack-up including dimensions of the 50 Ω coplanar microstrips implemented.
