A78

A78 / SMA78 Cascadable Amplifier 5 to 300 MHz Features • • • • HIGH DYNAMIC RANGE: +114 dB/ 1 MHz HIGH OUTPUT: +19.0 dBm (TYP.) HIGH THIRD ORDER I.P.: +35 dBm (TYP.) LOW NOISE FIGURE: 3.5 dB (TYP.) Rev. V3 Product Image Description The A78 RF amplifier is a discrete thin film hybrid design, which incorporates the use of 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. An active DC biasing network is used for temperaturestable performance, in addition to an RF Choke, used for power supply decoupling. Both TO-8 and Surface Mount packages are hermetically sealed, and MIL-STD-883 environmental screening is available.
