Discontinued: CobaltFx FET1854 Frequency Extension System, 18 to 54 GHz

CobaltFx cost-effective millimeter wave frequency extension system allows you to build a scalable and affordable 5G testing solution.

  • Frequency Range: 18-54 GHz
  • Connector Type: Coaxial NMD 1.85mm

Copper Mountain Technologies announced an End-of-Sale (EOS) for the FET1854 frequency extenders. This product is no longer available for purchase as of March 30, 2026. We will provide service and repair for owners of this instrument for a minimum of 3 years from the EOS date or based on parts availability.

Frequency range 18 GHz to 54 GHz
Measured parameters S-Parameters
Dynamic range 130 dB typ. (10 Hz IF BW)
Output power adjustment range -20 dBm to +3 dBm
Measurement time per point < 10 µs
Effective Source Match 36 dB
Effective Load Match 36 dB
Effective directivity 46 dB
Number of measurement point up to 500,001
