A70-2

A70-2 / SMA70-2 Cascadable Amplifier 10 to 250 MHz Rev. V4 Features  LOW NOISE: 2.2 dB (TYP.)  HIGH OUTPUT POWER: +19 dBm (TYP.)  HIGH THIRD ORDER I.P.: +38 dBm (TYP.)  LOW DC CURRENT: 25 mA (TYP.) AT +15 Vdc Description The A70-2 RF amplifier is a discrete hybrid design, which uses thin film manufacturing processes for accurate performance and high reliability. This single stage bipolar transistor feedback amplifier design displays impressive performance over a broadband frequency range. Use of an impedance transformer offers the benefit of high dynamic range and high efficiency. Both TO-8 and Surface Mount packages are hermetically sealed, and MIL-STD-883 environmental screening is available Ordering Information Product Image Part Number Package A70-2 TO-8 SMA70-2 CA70-2 ** Surface Mount SMA Connectorized ** The connectorized version is not RoHs compliant.
