The invention relates to an over-the-air (OTA) test system for measuring a performance of a device under test (DUT). The test system comprises an over-the-air (OTA) measurement chamber provided with at least one feedthrough for at least a first air hose and a second air hose. The test system further includes a thermally isolated hollow body inside the OTA measurement chamber, in which the DUT is positioned having at least two openings for connecting a first end of each of the first and the second air hose, and at least one sensor having a connection wire, located within the thermally isolated hollow body. Advantageously, the sensor connection wire is fed through one of the two openings into the thermally isolated hollow body.

Test system and method with a thermally isolated hollow body inside an over the air measurement chamber

An over-the-air test system for measuring the radiation performance as a function of temperature of a device under test is described, wherein the device under test has at least one antenna unit and at least one radio frequency circuit. The over-the-air test system comprises a measurement antenna unit, a measurement unit for at least one of signal generation and signal analysis, an enclosure that provides an internal space for accommodating the device under test for testing purposes in a sealed manner, and an atmosphere conditioning system that is configured to adapt the atmosphere within the internal space. The enclosure comprises at least one sealable opening via which the internal space is connectable with the atmosphere conditioning system to adapt the atmosphere within the internal space for the testing. Further, a method for measuring the over-the-air performance of a device under test is described.

Over-the-air test system as well as method for measuring the over-the-air performance of a device under test

An over-the-air measurement chamber is provided for performing measurements with respect to a device under test. The over-the-air measurement chamber includes a thermally isolated space inside the over-the-air measurement chamber, a positioner for positioning the device under test, and a first gas guiding means for intake of a gas and a second gas guiding means for outtake of the gas. The positioner comprises an inner portion and an outer rotational unit. The first and second gas guiding means are fed into the inner portion of the positioner through a hollow rotational axis of the outer rotational unit.

This invention relates to a hybridoma cell line which is capable of producing the monoclonal antibody G250. Furthermore, the invention describes the method of employing such cell line for the production and manufacture of monoclonal antibody G250 as well as derivatives thereof such as chimeric and humanized G250 antibodies.

Hybridoma cell line G250 and its use for producing monoclonal antibodies

A method for enhancing the therapeutic effect of cytokine treatment is disclosed. More specifically the present invention relates to a method for administering to a tumor patient a therapeutic dose of cytokine in combination with antibodies directed against the tumor associated antigen carbonic anhydrase IX (CAIX/G250/MN). The improved treatment method is characterized in a significantly reduced cytokine-related toxicity combined with potentiated effectiveness of anti-G250 antibody alone, resulting in a positive therapeutic response with respect to that observed with single anti-tumor agents alone.

The invention relates to a coaxial plug for connecting to a high-frequency transmission line. The housing of the coaxial plug has two slits arranged opposite each other, extending from the plug-side end in the axial direction, and both arranged and designed to form an axial abutment for receiving a BNC pin. A latching fork is arranged on the housing with two latching prongs tangentially overlapping an axial slit of the housing between the abutment and the plug-side end. Each BNC pin is held between a latching prong and an abutment of the axial slit, creating a locked connection between the coaxial plug and the BNC coaxial socket. The latching fork is pivotably arranged between a locking position in which the latching prongs tangentially overlap the axial slits, and a clearing position in which the latching prongs clear the axial slits over the entire length thereof.
