SPINNER produces components for automated tests that let users significantly reduce both work and costs. Supplementing its highly successful Easy Dock adapters, it is now also supplying low-PIM switches for test applications up to 6 GHz.
A surprisingly large share of low PIM RF component testing is still done manually. But there is enormous potential for reducing both labor and costs.
Although very similar approaches are taken for testing many products, many companies still aren’t fully tapping the available possibilities for streamlining them. For example, almost all manufacturers still use mobile radio antennas and radio units to measure VSWR and PIM. The methods they work with are quite similar, but practically without exception they involve laboriously inserting individual devices and cables between the objects being tested and the measurement equipment.
BN 754100 - SPINNER low-PIM switch 4.3-10 for up to 6 GHz
The newly developed SPINNER low-PIM switch has great potential for boosting the efficiency of testing. Technically it’s a double-pole, double-through (DPDT) crossover switch, also known as a switching matrix, with two inputs that are switched through to two outputs. It’s excellently suited for measuring VSWR and PIM, since it eliminates the need to laboriously disconnect and reconnect the test setup for each object. Plus, if multiple adapters and lines have been used they can either be eliminated completely or deployed more efficiently elsewhere. After each measurement, it’s only necessary to throw the switch to continue testing with different settings or devices. And if multiple tests need to be performed at the same time, a switching matrix can be assembled to operate several switches at once, depending on the required test path, and perform multiple measurements simultaneously.
These extremely low-PIM switches feature a service life of about 500,000 cycles and are specified for -165 dBc (typ. -170 dBc). They are available with 7-16 or 4.3-10 connectors for frequencies up to 3.8 GHz. We’re now also offering a new version with 4.3-10 connectors for up to 6 GHz.
Tests have shown that costs can be slashed by up to 80% by using switches and switching matrices, depending on how they’re configured.
