RF Shielded Enclosures
RF Shielded Enclosures
RF shielded enclosures — including rigid shielded boxes, portable shielded cases, and collapsible shielded tents — provide electromagnetic isolation for testing, measurements, and device operation in uncontrolled RF environments. By attenuating external radio frequency signals, these enclosures create a controlled electromagnetic environment that enables accurate over-the-air (OTA) testing, pre-compliance EMC measurements, and sensitive RF device characterization without requiring access to a dedicated anechoic chamber or Faraday cage. Typical shielding effectiveness ranges from 40 dB to over 80 dB depending on construction and frequency range.
Shielded enclosures are used extensively in telecommunications, wireless device development, IoT product testing, and electronics manufacturing. Portable shielded tents are particularly valuable for field testing and for laboratories that lack permanent shielded facilities, offering a cost-effective alternative for pre-compliance screening and RF isolation during development.
Typical Applications
- EMC pre-compliance radiated emissions and immunity screening in unshielded lab environments
- OTA wireless device testing (Wi-Fi, Bluetooth, cellular) in isolation from ambient RF signals
- RF-sensitive component and module characterization in R&D laboratories
- Temporary field testing and on-site diagnostic measurements
- Shielding small EUTs for NFC, RFID, and wireless module testing
