Q Series - Spread Spectrum OEM Modules

Q Series_1005

The family of military products are designed to meet the rigorous demands of military and government users world-wide. The Q Series is available as an OEM board level radio. The military products share the same features as our 900 MHz FGR 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.


  • Frequency Hopping or Single Frequency    
  • High Speed –115.2 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 and simultaneous Slave and Repeater function all in a single radio.    
  • Improved supply voltage range and power consumption. Input voltage range is now 7.5- 30 VDC at full RF output power. Receive current is less than 100 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 user-programmable 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.
