提出一种设计平面开关矩阵的方法。通过使用单刀单掷(SPST)芯片开关、芯片功分器和0 dB定向耦合器等简单电路实现开关矩阵的平面拓扑。由于射频电路使用键合工艺将芯片、微带无源电路进行连接,因此与传统开关矩阵相比,具有体积小、重量轻、工艺简单、可靠性高的特点。最后通过对一个X波段2×3平面开关矩阵设计和测试,证明了该设计的有效性。 A method of designing planar switch matrix is ​​proposed. The planar topology of the switch matrix is ​​achieved by using simple circuits such as single-pole-single-throw (SPST) chip switches, chip dividers, and 0 dB directional couplers. Compared with the traditional switch matrix, the RF circuit has the advantages of small size, light weight, simple process and high reliability because the RF circuit uses the bonding process to connect the chip and the microstrip passive circuit. Finally, the design and test of an X-band 2 × 3 planar switch matrix is ​​proved to be effective.
