UsedBuy It NowBest Offer

Avantek UTC5-164M RF Amplifier 5-500MHz 24VDC (Tested & Working!)

For sale are working Avantek UTC5-164-1 amplifiers! Rated for 5-500 MHz on the case, but the spectrum analyzer photo you see in photos 2 & 3 show the actual upper 3-dB point to be around 1.4 GHz. Your mileage may vary depending on the unit, but I would expect them to exceed the specifications set by miles (or at least a few hundred MHz).
