The A77-1 RF amplifier is a discrete hybrid design, which
incorporates the use of thin film manufacturing processes
for accurate performance and high reliability.
The single stage silicon bipolar transistor feedback amplifier design displays impressive performance over a broadband frequency range. An active DC biasing network is used for temperature-stable 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.
