    For working range from 5.. to 400MHz it proves it is withing specs, although it is obviously optimized for RF use and Sinusoidal signal shape, and have less quality square signal shape for digital signal/clock use. Look at the pictures below.

    It works! I measure about 12-17 dB at 5665MHz and 433MHz. There are no any ESD protection bag, no end-cup, no antistatic bag. But the chip has inner ESD protection 1000V. The chip is SBB5089Z - InGaP amp up to 6GHz. The shield has laser engraving name and description! I like this amp!

    The product is really ok. It is great for amplifying weak signals up to 100 mw. Great for WSPR signals when the entry is 10 mw as it has the RaspberryPI GPIO

    Great product and quality, tested in raspberry pi, with Pifm to transmit great gain, and put in Baofeng to RX, easy to connect.

    Tested to 2.5gig, approximately 20db of gain measured as described. Good small wide band amplifier.

    Good RF amp. Can't get much better at this price.

    For the price - unbeatable. The MMIC alone would probably cost more.
