Benefits of An RF/Microwave Switch Matrix
The purpose of a switch matrix is to move the signal routing and signal conditioning to one central location in the test system versus having it all distributed at various places in the test system. Moving the signal routing and signal conditioning to a single location in the test system has the following advantages:
- The calibration plane between the DUT and test equipment becomes smaller and more centralized, making it easier to characterize.
- Switches and signal conditioners have similar power, mounting, and driver requirements, so moving them to a single location means only a single power supply and driver circuit is needed to power and control them.
- Short signal paths reduce insertion loss and increase signal integrity.
- Exact-length signal paths are possible, thereby controlling phase issues.
- Simplifies service and support.

“As all historians know, the past is a great darkness, and filled with echoes. Voices may reach us from it; but what they say to us is imbued with the obscurity of the matrix out of which they come; and try as we may, we cannot always decipher them precisely in the clearer light of our day.”
—Margaret Atwood (b. 1939)
