Products Unlicensed Radio Telemetry and SCADA Modems MHX-920 - Professional OEM Wireless Modems

MHX-920 - Professional OEM Wireless Modems

Top End Performance

The highest performance modem!  
MHX-920 is the fastest Frequency Hopping serial radio ever - 230.4kbps!

Excellent Sensitivity -112dBm gives long range communication.

Very High rejection eliminates the need for expensive and cumbersome cavity filters required with other radios.

Power adjustable in 1dB levels give you the highest system gain by exactly complying with the 36dBm ERPI.

Dual ports allow for real time diagnostics and transparency. Diagnostic Tools including Internal Spectrum and Network Analyzer gives real time Site Surveys.

MHX-920 features 128Bit Encryption Key to protect your system.

Internal Frequency Segmentation allows simple frequency planning for fixed and roaming applications.

Fast Frequency Hopping, Low latency, High throughput gives you the wired-like performance over long range.

Low operating current consumption - receive,  sleep, sniff, shutdown. 

The MHX-920 is available in the standard footprint or with a high voltage option
