A81-1 / SMA81-1 Cascadable Amplifier 20 to 250 MHz Rev. V3 Features • • • • Product Image High Reverse Isolation : >30 dBm (TYP.) Low Noise: 2.4 dB (TYP.) High Gain: 25 dB (TYP.) High Level Output: +13.5 dBm (TYP.) Description The A81-1 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. Ordering Information Part Number Package A81-1 TO-8 SMA81-1 Surface Mount CA81-1** SMA Connectorized ** The connectorized version is not RoHs compliant.
