Detailed description of the invention
In order to make those skilled in the art be more fully understood that the present invention program, and it is understandable to enable the above-mentioned purpose of the present invention, feature and advantage to become apparent from, and below in conjunction with embodiment and embodiment accompanying drawing, the present invention is further detailed explanation.
nullAs shown in figs 2-4，A kind of radio-frequency filter test fixture，Utilize this test fixture can measure the radio-frequency filter of multiple electrode position specification，Clamp block 2 and at least two radio frequency being detachably secured on clamp block 2 including cuboid connect terminal 4，One as signal input terminal，One as signal output terminal，Radio frequency connects respectively terminals 6, two ends of terminal 4、Test lead 8，Terminals 6 are connected with test instrunment by radio frequency electrical cable，Test lead 8 is directly connected with the electrode of radio-frequency filter，Being particular in that of the present invention is provided with at least one conduction trough 14 on a side surface of clamp block 2，Two be preferably arranged side by side，And the line of centres of two conduction troughs 14 is parallel with the long limit of clamp block 2，Concrete，The both side surface of conduction trough 14 through clamp block 2 thickness direction，Multiple radio frequencies connect terminal 4 traverse conduction trough 14，And terminals 6 and test lead 8 are exposed independent from the outside of conduction trough 14，Placement space is provided to multiple radio frequencies connection terminal 4 by arranging conduction trough 14，Radio frequency is connected terminal 4 and is optionally arranged on diverse location by the size according to filter electrode position，Thus reaching to measure the purpose of the radio-frequency filter of Different electrodes position size，Compatible good.
All it is equipped with multiple radio frequency in two conduction troughs 14 and connects terminal 4, and multiple radio frequency connect terminal 4 be parallel to each other, side by side, the setting at interval, by the diverse location in conduction trough 14, radio frequency connection terminal 4 is installed and can be combined into multiple air line distance, such that it is able to measure the radio-frequency filter of multiple electrode position size.
