ANTENNA ADAPTER Russian patent published in 2002 - IPC

FIELD: radio-frequency test equipment for portable radiotelephones. SUBSTANCE: in the preferable modification the adapter assembly has a radio-frequency connector on one end of the elongated conductor that is directly connected to the antenna lead of the radiotelephone substituting for the ordinary antenna assembly. The elongated conductor accomplishes an electric contact with the external grounding of the leads for loading charge of the storage cell in the lower part of the radiotelephone on the other end. The radio-frequency connector may be matched in impedance for reduction of attenuation of the RF signal at a connection to the radio-frequency test equipment. In one of the modifications the radio-frequency connector is a 50-Ohm connector, type SMA, matched in impedance. EFFECT: provided integration of the radiotelephone with the test equipment with minor introduced loss. 27 cl, 10 dwg
