Operational Features • Designed specifically for airborne use TETRA Airborne Transceiver with SIM Card Facility Chelton 7-450-15 TETRA Airborne Transceiver with SIM Card Facility provides airborne users with access to TETRA (TErrestrial Trunk RAdio) communications networks. The transceiver uses the feature-rich Sepura® SRG3900TM core radio, and operates in one of the standard TETRA frequency bands, from 380 MHz to 430 MHz. The 7-450-15 includes a mechanically sealed access port for the insertion and removal of a SIM card. The SIM card facilitates storage of radio "personality" and end-to-end cryptographic information. The 7-450-15 interfaces directly to standard aircraft audio systems and is compatible with Chelton CH150 and CH250 Control and Display Units (CDU) and the optional RH150 remote CDU. The transceiver operates with a UHF antenna; recommended types are Chelton 21-68 or 21174. All 7-450-15 transceivers feature integrated Global Positioning System (GPS) receivers, which provide own-platform position information onto the TETRA network and to the CDU. Recommended GPS antennas are the Chelton Type 20-41 or Chelton SATCOM's CI 408-20. The unit is housed in a % ATR size black aluminium alloy enclosure with a hold down point and a carrying handle on the front face. The connector interfaces are accessible from the front faceplate of the unit. The unit is designed to be rack mounted in a short tray. - Compatible with common aircraft audio distribution system signal levels and impedances - In-circuit RF bandpass filter provides immunity from on board transmitters in the VHF and IFF bands and protection to existing aircraft systems, particularly the VHF communications and navigation receivers - Differential transmission of CDU transceiver control signals ensures noise immunity - Transient suppression and regulation of aircraft 28 V power supply provides a stabilised supply to the core radio module even during momentary supply interruptions - Provides 5 V on the RF coax to power a GPS antenna • Radio "personality" and end-to-end cryptographic information delivered through the SIM card.
