22、onnector interface specified by this part of IEC 1169 includes patented matter which is contained in a United States patent assigned to the manufacturer. The International Electrotechnical Commission calls attention to the fact that certain interface dimensions and features of the BMA connector are
23、the subject of the United States patent no. 4,426,127 now issued and owned by M/A-Com Omni Spectra, Inc. The IEC takes no position with respect to patent validity. M/A-Com Omni Spectra has assured the IEC that it is willing to grant a licence under these patents on reasonable and non-discriminatory
24、terms and conditions to anyone wishing to obtain such a licence. M/A-Com Omni Spectras undertakings (policy letter on licensing, the licence offer, and the form of licence) in this respect are on file with the International Electrotechnical Commission and are available for inspection by all interest
25、ed parties at the IEC Central Office. The licence details may be obtained from the legal department of M/A-Com Omni Spectra, Incorporated whose address is: 1 Scope Series BMA connectors have a characteristic impedance of 50 7 and are normally used for blind-entry low-power microwave applications in
26、conjunction with flexible and semi-rigid cables having a dielectric diameter of up to 3,00mm. The connectors are usable up to a frequency of at least 18GHz. This sectional specification provides information and rules for the preparation of detail specifications for series BMA r.f.connectors together

43、rd test connectors, plug (Grade 0) 2.4 General requirements for connector mounting in modules and on panels 2.4.1 Limits of permissible connector radial misalignment and axial misalignment When designing the mounting arrangements for series BMA connectors, it is essential that the disposition of ind
44、ividual pairs of connectors and their engagement is controlled within the following general limiting conditions. 2.4.1.1 Radial misalignment The radial misalignment between engaging connectors refers to the concentricity error between diameterg of the plug and diameter f of the socket at the beginni
45、ng and during the engagement (see2.1 for dimensionsg and f of the plug and socket. A rigidly mounted plug and socket shall accept a radial misalignment within at the beginning and during the engagement. A rigidly mounted plug and float-mounted socket shall accept a radial misalignment within at the
46、beginning of the engagement. During the engagement, the floating connector shall be able to align itself with the rigidly mounted connector within 2.4.1.2 Axial misalignment a) Rigidly mounted plug and socket To maintain the electrical and environmental performance, the connector reference planes sh
47、ould be within 0,015 in (0,38mm). Further separation up to 0,030 in (0,76mm) will degrade electrical performance and negate the environmental performance. b) Rigidly mounted plug and float-mounted socket The float mounting allows a total of 0,060 in (1,52mm) axial travel. The mounting arrangements s
48、hould, however, ensure a minimum length of travel of 0,010 in (0,26mm) 0,030 in (0,76mm) preferred to ensure that full length of engagement is maintained under operational conditions.
