Rectangular Horn Antennas
-
SAGE Millimeter wave rectangular gain horns, also called pyramidal gain horns, are offered as both standard and custom models with a rectangular waveguide interface. The pyramidal gain horns only support linear polarization. With a calibrated gain chart, these horns can be used to measure the gain of other antennas by comparing the generated signal levels of both. For this reason, these horns are also referred to as standard gain horns. The listed models offer 23 dB nominal gain, 10/11 degrees typical half power beamwidth and 14 dB/30 dB typical side lobe levels at the center frequency of the band. These horns cover full waveguide bandwidths within the frequency range of 8.2 to 170 GHz. In addition to the models listed below, models with 10, 15, 20 and 25 dB gain and other frequency bands are also available.

Debug Fixture
-
With at-speed test, debug can easily become a problem: If test points are on the bottom, as is often the case for test processing, then this requires the board to be flip over for the debug. However, during at-speed testing, key devices and signal paths are often on the topside. IST Engineering has in-house expertise with debug fixtures, which allow the test technician to flip over a test board, or even hold it vertically for dual-sided access, while still running the Device-Under-Test at full-speed through card-edge connectors - whether these are standard DIN type or F or N type co-ax connectors. The debug stations are constructed robustly, with metal frames and high-grade flexible cabling and can also be used as backup test stations in a manufacturing flow. They can be built with custom machined waveguide connections for RF/Microwave applications, or with standard, off the shelf connectors, as defined by the application. A number of these debug fixtures are in production use with a range of customers.
