また、例えば高周波信号切替スイッチ１２Ｅのスイッチ素子ＨＳ１と、高周波信号切替スイッチ１２Ｆのスイッチ素子ＨＳ８と、高周波信号切替スイッチ１２Ｇのスイッチ素子ＨＳ８と、高周波信号切替スイッチ１２Ｈのスイッチ素子ＨＳ１とをそれぞれ同時にスイッチオン制御することにより、高周波信号切替スイッチ１２Ｅの信号入力端ＩＮ１に入力された第５チャンネル（５ＣＨ）の高周波信号が信号出力端ＯＵＴ４に出力され、高周波信号切替スイッチ１２Ｆの信号入力端ＩＮ６に入力された第６チャンネル（６ＣＨ）の高周波信号が信号出力端ＯＵＴ８に出力され、高周波信号切替スイッチ１２Ｇの信号入力端ＩＮ７に入力された第７チャンネル（７ＣＨ）の高周波信号が信号出力端ＯＵＴ５に出力され、高周波信号切替スイッチ１２Ｈの信号入力端ＩＮ８に入力された第８チャンネル（８ＣＨ）の高周波信号が信号出力端ＯＵＴ１に出力される。   Further, for example, the switch element HS1 of the high-frequency signal selector switch 12E, the switch element HS8 of the high-frequency signal selector switch 12F, the switch element HS8 of the high-frequency signal selector switch 12G, and the switch element HS1 of the high-frequency signal selector switch 12H are simultaneously switched. By performing the ON control, the high frequency signal of the fifth channel (5CH) input to the signal input terminal IN1 of the high frequency signal selector switch 12E is output to the signal output terminal OUT4 and input to the signal input terminal IN6 of the high frequency signal selector switch 12F.

これら各チャンネルの高周波信号の入出力において、上記各信号入力端から信号出力端までの配線長（伝搬距離）は、それぞれ、等しい長さ（距離）である。このように、高周波信号の信号入力端から信号出力端までの配線長（伝搬距離）を一様に揃える（配線長のばらつきを抑制する）ことにより、高周波信号の高速切替が可能となる。   In the input / output of the high-frequency signal of each channel, the wiring length (propagation distance) from each signal input end to the signal output end is the same length (distance). As described above, by uniformly aligning the wiring length (propagation distance) from the signal input end to the signal output end of the high-frequency signal (suppressing variations in the wiring length), it is possible to switch the high-frequency signal at high speed.

この高周波信号の信号入力端から信号出力端までの配線長（伝搬距離）のばらつきによる、挿入損失とＳＷＲ（反射の度合い）の関係を図５乃至図７に示している。図５は上記したマトリクス配線領域１１と同等のマトリクス配線上において、Ｘ信号線ＸＬ（またはＹ信号線ＹＬ）の一端を入力端、他端を出力端とした場合、図６は同じく上記マトリクス配線上において、Ｘ信号線ＸＬ（またはＹ信号線ＹＬ）の一端を入力端、当該線上の１／２を出力端とした場合、図７は同じく上記マトリクス配線上において、Ｘ信号線ＸＬ（またはＹ信号線ＹＬ）の一端を入力端および出力端とした場合の、模式図（ａ）と特性図（ｂ）とを示している。この図５乃至図７に示すように、挿入損失Ｓ２１、およびＳＷＲＳ１１は、信号入力端から信号出力端までの配線長（伝搬距離）によって特性を異にする。従って複数の高周波信号を同時に切替制御する切替回路において配線長（伝搬距離）を一様化することで、取り扱う画像生成用の複数の高周波信号に対して安定した高品位の高速切替が可能となる。   The relationship between insertion loss and SWR (degree of reflection) due to variations in the wiring length (propagation distance) from the signal input end to the signal output end of the high-frequency signal is shown in FIGS. FIG. 5 shows a case in which one end of the X signal line XL (or Y signal line YL) is an input end and the other end is an output end on the same matrix wiring as the matrix wiring region 11, and FIG. In the above, when one end of the X signal line XL (or Y signal line YL) is an input end and ½ on the line is an output end, FIG. 7 also shows the X signal line XL (or Y on the matrix wiring). A schematic diagram (a) and a characteristic diagram (b) in the case where one end of the signal line YL) is used as an input end and an output end are shown. As shown in FIGS. 5 to 7, the insertion loss S21 and the SWRS 11 have different characteristics depending on the wiring length (propagation distance) from the signal input end to the signal output end. Therefore, by making the wiring length (propagation distance) uniform in a switching circuit that controls switching of a plurality of high-frequency signals at the same time, stable and high-quality high-speed switching can be performed for a plurality of high-frequency signals for image generation to be handled. .

上記した本発明の第１実施形態に係る多チャンネル高周波信号切替装置は、四辺形のマトリクス配線領域１１を囲繞するように８組の高周波信号切替スイッチ１２Ａ〜１２Ｈを設けた構成であることから、８チャンネルの任意の組み合わせによる高周波信号の切替回路をコンパクトに構成でき、切替回路の配線長を短縮できる。これにより伝送ロスの少ない多チャンネル（８×８チャンネル）の高周波信号切替装置が実現できる。また、四辺形のマトリクス配線領域１１において、配線層ＳＡ，ＳＢ相互の間と、配線層ＳＢと他方の表層ＰＢとの間にベタパターンのグランド層ＧＮＤが挿入されていることから高周波信号切替スイッチ１２Ａ〜１２Ｈ相互の間の信号漏れを抑制した高周波信号切替装置が実現できる。さらに上記したように各チャンネルの配線長（伝搬距離）が一様化されることで、安定した高品位の高速切替が可能となる。   The multi-channel high-frequency signal switching device according to the first embodiment of the present invention described above has a configuration in which eight sets of high-frequency signal switching switches 12A to 12H are provided so as to surround the quadrilateral matrix wiring region 11. A high-frequency signal switching circuit using an arbitrary combination of eight channels can be configured in a compact manner, and the wiring length of the switching circuit can be shortened. As a result, a multi-channel (8 × 8 channel) high-frequency signal switching device with little transmission loss can be realized. In addition, in the quadrilateral matrix wiring region 11, a solid pattern ground layer GND is inserted between the wiring layers SA and SB, and between the wiring layer SB and the other surface layer PB. A high-frequency signal switching device that suppresses signal leakage between 12A to 12H can be realized. Furthermore, since the wiring length (propagation distance) of each channel is made uniform as described above, stable high-quality high-speed switching becomes possible.

上記した多チャンネル（８×８チャンネル）の高周波信号切替装置を複数組み合わせて、より多チャンネルの高周波信号切替装置を実現した構成例を図８に示している。この図８に示す構成例は、上記図１乃至図４に示した高周波信号切替装置（ここでは８×８マトリクス回路と称す）を前後段各４組ずつ計８組用い、前段の４組の８×８マトリクス回路５１〜５４の任意の２チャンネルの出力端を後段の４組の８×８マトリクス回路５５〜５８の任意の２チャンネルの入力端に接続することによって所望の多チャンネル切替回路を実現している。ここでは入力３２チャンネル、出力最大３２チャンネルの任意切替可能な高周波信号切替装置を実現している。このような多チャンネル切替回路を、さらに階層化して接続することにより、より多チャンネルの高周波信号切替装置を実現することができる。   FIG. 8 shows a configuration example in which a plurality of multi-channel (8 × 8 channel) high-frequency signal switching devices are combined to realize a multi-channel high-frequency signal switching device. The configuration example shown in FIG. 8 uses the high-frequency signal switching device (referred to as an 8 × 8 matrix circuit here) shown in FIGS. A desired multi-channel switching circuit can be obtained by connecting the output terminals of any two channels of the 8 × 8 matrix circuits 51 to 54 to the input terminals of any two channels of the four sets of 8 × 8 matrix circuits 55 to 58 in the subsequent stage. Realized. Here, an arbitrarily switchable high-frequency signal switching device with 32 input channels and 32 maximum output channels is realized. By connecting such multi-channel switching circuits in a hierarchical manner, a multi-channel high-frequency signal switching device can be realized.

The intersection (XL4 · YL5) of YL5 is the high-frequency signal output terminal OUT4 of the fourth channel, and the intersection (XL5 · YL4) of XL5 and YL4 is the intersection of the high-frequency signal output terminal OUT5 of the fifth channel, XL6 and YL3 (XL6 · YL3). Is the intersection of the sixth channel high-frequency signal output terminal OUT6, XL7 and YL2 (XL7, YL2) RF signal output terminal of the seventh channel OUT7, XL8 the intersection of YL1 a (XL8 · YL1) is set to the eighth channel of the high frequency signal output terminal OUT8.

このような第２実施形態の構成においても、四辺形のマトリクス配線領域１１の一辺を２０mm乃至３０mm程度にすることで、切替回路の配線長を一律に短縮でき、現況の数十メガヘルツ〜百数十メガヘルツの高周波信号の高速切替に十分に適用可能なコンパクト形の多チャンネル高周波信号切替装置が実現できる。   Also in the configuration of the second embodiment, the wiring length of the switching circuit can be uniformly reduced by making one side of the quadrilateral matrix wiring region 11 about 20 mm to 30 mm, and the current tens of megahertz to hundreds A compact multi-channel high-frequency signal switching device that can be sufficiently applied to high-speed switching of a 10 MHz high-frequency signal can be realized.

Thus, switching of multi-channel high-frequency signals can be easily realized with a small circuit configuration.
