STE2800 RF Shielded Test Enclosure

Designed around the STE2200, we took the task of repeatability testing of TDMA, CDMA, AMPS, PCS and GMS phones, and other wireless communications to a new level! For more than a decade Ramsey’s RTF Radiating Test Fixture was the standard in pager testing and alignment. Now, designed specifically for such communications devices, the RTF has a built-in embedded antenna to cover 800 MHz to 8 GHz.

A heavy duty universal clamp system allows any phone to be securely clamped into position for testing. Once clamped in, the flat coupling response, together with the high RF Isolation factor, gives you guaranteed repeatability testing. Phone to phone, the measurements will be exact, and will be taken under the identical conditions. A Type-N connector is provided standard on the STE2800 for the RTF antenna connection. Other I/O connector options may be ordered separately.

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.
