    Broadband Pre-amplifier UBBV DC20


    Works with any brand of Spectrum Analyzers and directly fits to any SPECTRAN e.g. the SPECTRAN V5. Broadband sensitivity increases by up to 15dB.


    Newly designed microwave chips enable the UBBV DC20 to have gain up to 20GHz. The UBBV DC20 is the ideal general purpose RF amp that you'll wonder how you got along without.

    Enables maximum performance particularly when measuring extremely weak signals.

    A "must have" to get the maximum performance out of any SPECTRAN V5 unit.
