SMPS converter and a LDO that source the system ASIC. The current drawn by the JODY-W2 series through the VBAT pin can vary by several orders of magnitude depending on the operation mode and state. It changes from high current consumption during Wi-Fi transmission at maximum RF power level in connected-mode to low current consumption during low power idle-mode with the power saving configuration enabled.
The SMPS is the ideal choice when the available primary supply source has significantly higher value than the operating supply voltage of the JODY-W2 series modules. The use of SMPS provides the best power efficiency for the overall application and minimizes current drawn from the main supply source.

JODY-W2 antenna reference design, application note [15]. • The ANT0 and ANT1 pins of JODY-W2 have a nominal characteristic impedance of 50 and must be connected to the external antennas through a 50 transmission line to allow proper RF transmission and reception.
JODY-W2 - System integration manual 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 reference designs. Reference design source files can be provided on request by u-blox.
Design-in 2.1 Overview For an optimal integration of JODY-W2 series modules in the final application board, it is advisable to follow the design guidelines described in this chapter. Every application circuit must be properly designed to ensure that the related interface functions correctly, but several specific points require special attention during the design of the application device.
JODY-W2 - System integration manual RF transmission line design RF transmission lines such as the ones from the ANT0 and ANT1 pins up to the related antenna connectors must be designed so that the characteristic impedance is as close as possible to 50 .
