    Application examples

    • A "must have" for EMC measurements
    • Amplification of very weak signals
    • Boosts any antenna gain
    • Compensation of negative antenna gain


    • Currently there are no additional options available.


    • USB Cable (UBBV)

      To connect your external preamplifier to the PC. Special version with high performance EMC-ferrite. Highly recommended for PC use. You can find more product details in our online shop.

    • 1m, 5m or 10m Low Loss SMA Cable

      High quality special SMA cable for connecting any HyperLOG®-Antenna or BicoLOG®-Antenna or the preamplifiers UBBV Series with various test equipment like Aaronia RF Spectrum-Analyzer. You can find more details about the article in our online shop.

    • SMA to N Adapter

      To connect any Spectrum Analyzer etc. with N connector to the HyperLOG antenna (Above SMA cable needed). You can find more details in our online shop.

    • 20dB SMA Attenuator

      Expands the measurement range from +20dBm to +40dBm. More product details in our online shop.

    • DC-Blocker (SMA)

      The DC-Blocker must be used if you want to measure DC powered signals like DSL/ISDN lines. It prevents the RF-input of the SPECTRAN from being destroyed by the DC-voltages. Simply connect the DC-Blocker to the SMA-input of your SPECTRAN. More product details in our shop.

    40dB RF Broadband Preamplifier UBBV2


    High-End RF Preamplifier up to 10GHz. Works with any brand of Spectrum Analyzers and directly fits to any SPECTRAN. Broadband sensitivity increase by up to 40dB.


    Problems to read weak signals? Or how about boosting that probe gain or maybe preamping that antenna?
    The UBBV2 broadband preamp is the answer to all these needs as well as many others. You can use the UBBV2 anywhere a high gain, low noise amp is called for; digging out those weak shortwave signals or putting new life into that analyzer especially in the frequency range below 1GHz.
    Since the UBBV2 has such a high compression point of almost 100 milliwatts, you can even use it to boost the power of small micro transmitters!
    Newly designed microwave chips enable the UBBV2 to have gain up to 12GHz although we only spec the UBBV2 to 10 GHz. The UBBV2 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. Highly recommended for EMC and Pre-Compliance tests like EN55011, EN55022, EN50371 etc..

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