De-embedding S-parameters to remove the effects of a test fixture.

De-embedding S-parameters to remove the effects of a test fixture. Performing S-parameter measurements on RF components can be quite challenging. The problem arises from the fact that the connections of typical RF components, for example SMD components, cannot be connected directly to a VNA because, of course, they do not have coaxial connectors. Therefore, some type of fixture is needed that houses the SMD part and connects it to coaxial connectors (Picture 1). However, this fixture with its connectors and 'wiring' will affect, often seriously, the measurement of the RF p [...]  Read more >

RF Enclosure Mini-Extended-FX: a new universal enclosure for RF circuits

RF Enclosure Mini-Extended-FX: a new universal enclosure for RF circuits The RF Enclosure MINI-EXT-FX is a new line of RF enclosures that speed up your RF development project by creating housing, high-performance SMA ports, RF grounding, and thermal stability all in one go. Best of all, replacing the PCB with a new revision is easy, so the enclosure can be reused for your next project.  The RF MINI-EXT-FX can be conveniently used in small-series production. The EXT designation refers to the doubled length of the PCB that fits in the enclosure, compared to the MINI version. The [...]  Read more >

SMA connector performance in the RF Enclosure Mini used as a PCB test fixture

SMA connector performance in the RF Enclosure Mini used as a PCB test fixture One of the most common reasons to use an RF enclosure from the Gquipment Mini series is to house some RF/microwave PCB to create an RF module with some specific function. To evaluate the design criteria of this function, one must measure the RF module—for example, by measuring its S-parameters with a VNA using the RF ports of the RF Enclosure Mini. Then, the RF PCB is the DUT, and the RF Enclosure Mini is used as a test fixture. Of course, the influence of the RF ports should be minimal; however, in practi [...]  Read more >
