SMA81-2 MACOM

A81-2 / SMA81-2 Cascadable Amplifier Rev. V3 20 to 500 MHz Features Product Image HIGH OUTPUT POWER: +15.0 dBm (TYP.) HIGH EFFICIENCY: 29 mA +15 Vdc (TYP.) LOW NOISE 2.9 dB (TYP.) HIGH GAIN: >24.5 dB (TYP.) Description The A81-2 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.
