Abstract
An evaluation device includes a holder that holds the radio communication module, a measurement antenna that transmits and receives radio waves for measurement, and a temperature regulator that adjusts a temperature of the radio communication module. The temperature regulator is in direct or in indirect contact with the radio communication module so as to be capable of transferring heat.
Claims11
An evaluation device of a radio communication module, comprising:
- a radio communication module that is to be evaluated and that includes an antenna pattern, RFIC and a substrate,
- a holder that holds the radio communication module, the holder is a separated body from the radio communication module, and is in contact with a first surface of the substrate, and
- a measurement antenna that is disposed so as to face the radio communication module, and that transmits and receives radio waves for measurement, and
- a temperature regulator that adjusts a temperature of the radio communication module, and that is disposed in a position so as to face to a second surface which is opposite to the first surface of the substrate, wherein
- the temperature regulator is in direct or in indirect contact by solid intervening material with the RFIC of the radio communication module so as to be capable of transferring heat,
- wherein
- the holder is a plate which includes a through opening,
- the through opening includes the antenna pattern as seen from a thickness direction of the holder, and
- the holder fixes the radio communication module by a pressing force that presses the radio communication module against the temperature regulator.
