| Cascadable Amplifier 20 to 500 MHz Features * * * * HIGH REVERSE ISOLATION >35 dBm (TYP.) EXCEPTIONAL OUTPUT VSWR 1.1:1 (TYP.) LOW NOISE 3.6 dB (TYP.) MEDIUM OUTPUT LEVEL +8.0 dBm (TYP.) A81-3/ SMA81-3 V2 Product Image Description The A81-3 RF amplifier is a discrete hybrid design, which uses thin film manufacturing processes for accurate performance and high reliability. The 2 stage silicon bipolar feedback amplifier design displays impressive performance over a broadband frequency range. An isolation transformer is used in the feedback loop, with the benefit of high reverse isolation. Both TO-8 and Surface Mount packages are hermetically sealed, and MIL-STD-883 environmental screening is available.
