Narrow Band 225 - 400MHz Spread Spectrum Radios
The family of military products are designed to meet the rigorous demands of military and government users worldwide. The 225-400 MHz is available as an OEM board level radio. The military products share the same features as our 900 MHz M-Series, including 32-bit CRC error detection with automatic retransmission, and single radio repeater. Our military products provide reliable data communications in the most adverse environments.
- 25 kHz Channel Spacing
- Frequency Hopping
- High Speed –19.2 Kbps true throughput.
- Long Range – 60+ mile range with clear line of sight, ability to extend through repeaters.
- Error Free Communications – 32 bit CRC with automatic retransmission.
- Industrial Grade Specifications – 100% tested for full performance from -40°C to +75°C.
- Repeater function in a single radio.
- Improved supply voltage range and power consumption. Input voltage range is now 9.5- 30 VDC at full RF output power. Receive current is less than 250 mA @ 12 VDC.
- Separate diagnostic serial connector allows real time local diagnostics and setup menu access.
- Better diagnostics, including signal level in dBm and transmit current.
- RS485/RS232 Interface. In addition to RS- 232, the FGR Series is now available with a userprogrammable RS-232/RS-485/RS-422 interface.
- Noise Immunity – Superior performance in noise congested environments.
- Secure – proprietary spread spectrum technology prevents detection and unauthorized access.
