SMA231

A231 / SMA231 Cascadable Amplifier 10 to 250 MHz Rev. V3 Features  LOW NOISE FIGURE: 1.7 dB (TYP.)  HIGH GAIN: 26.0 dB (TYP.)  HIGH EFFICIENCY: 16 mA at +5 Vdc  MEDIUM OUTPUT LEVEL: +14 dBm at +8 Vdc (TYP.) Description The A231 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.
