1 Scope
This document defines the essential specifications necessary to implement the JODY-W1 antenna
reference designs. It is part of the equipment certification application issued to FCC and IC. The
information contained herein and its references should be sufficient to guide a skilled person in an
attempt to implement the design on a host carrier. It will provide the designer with PCB layout
details and expected performance specifications.
The document supports a connector-based designs for the use of external antennas (one for each
antenna pin of the module)

3 General description and requirements
JODY-W1 series module provides three RF interfaces for connecting the external antennas.
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; a bad termination of the pin may result in poor performance or even
damage to the RF section of the module.
The ANT2 antenna port is not used on the JODY-W164-03A and JODY-W164-07A modules.
For optimal antenna performance in multi-radio mode, the isolation between the antennas must be
maximized; the designer must follow the requirements specified in Table 2 and Table 3 to ensure
good performance.
