Cascadable Amplifier 10 to 1500 MHz A28-2/ SMA28-2 V3 Features • • • • Product Image LOW NOISE: 3.5 dB (TYP.) HIGH EFFICIENCY: 27 mA (TYP.) @ +5 Vdc GOOD DYNAMIC RANGE: 105 dB (TYP.) LOW VSWR: <1.4:1 (TYP.) Description The A28-2 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.
