STE2300 RF Shielded Test Enclosure

As isolated RF testing evolved into more applications, so did the size, design, and style of the enclosures. The STE2300 was designed as the little brother and smallest STE available for small wireless devices. As wireless LAN devices became smaller, it made sense to step-up the STE2300 to a slightly larger design that also utilized our standard universal I/O interface panel. This not only allowed the testing of larger devices, but gave the user the same I/O capacity of our largest enclosures.

RF Shield Box STE2300 Key Benefits

The STE2300 is constructed to the same precision-machined tolerances as our larger enclosures to maintain an exceptionally well shielded environment. The universal I/O panel is constructed of heavy duty milled 304 stainless steel to assure stability even when well populated with I/O connectors and feedthroughs. Heavy duty, .090 and .125 aluminum is used throughout and our double lip, high performance RF gaskets are used at all joint locations assuring a reliable RF tight closure. Oversized hinges and latches are used to provide a physically tight seal every time. In addition, steady-hold hinges keep the access door at any fixed position making repetitive production testing easier. RF absorbent foam lines the interior to provide a typical RF attenuation of -90dB @ 3GHz makes the STE2300 an ideal cross-over chamber for smaller devices that do not require a larger area or hands-on manipulation.

  • The larger brother of the STE2200
  • Rear-mounted I/O panel for custom configuration
  • Easy-snap latch for repetitive lab use
  • Steady-hold hinge
  • Designed to larger wireless devices requiring additional real time RF and power connections

RF Shield Box STE2300 Specifications

Size wise, we increased the width to 9 inches, the height to 5 inches and the depth to 12 inches. This together with the extended I/O capacity gives the user all the benefits of the larger enclosures while keeping closely within size of his DUTs. And that’s a cost savings. In addition to the standard universal I/O panel we also designed in the option for cross ventilation to cool the DUT. For the first time these advanced features became available in a small hand-held test chamber!

Note: RF Isolation specs are measured at 1M with terminated RF feedthrough coaxial connectors installed. Actual isolation & attenuation can be affected by adding additional filtered and non-filtered connectors. Check with us for specific connector specifications. STE series I/O interfaces, connectors, and options are frequently updated. Check with us for updates.
