Abstract
A microwave amplifier device with a bypass segment, the device operating either in active mode or in bypass mode. The bypass segment () comprises at least one section () of coupled transmission lines () whereby the isolation is increased. The amplifier unit () includes two LNAs arranged in parallel in a balanced configuration, and the bypass segment () has a relatively high input impedance in active mode, whereby a balanced operation of the amplifier unit is maintained. Consequently, a low noise factor is obtained, as well as reduced input and output reflections.
