Mini-Circuit's Blue Cell technology allows the use of its 90-degree splitters to enhance the performance of
a family of medium power amplifiers. Balanced amplifier configurations offer several performance
advantages when compared to single-ended designs. The foremost advantage is the improvement of both
input and output return loss due to reflections canceling in the hybrid couplers. Amplifier design stability is
also more predictable due to each active device being terminated in a 50-ohm load. Furthermore, output
power and third order intercept performance are twice that of a single device amplifier. Lastly, if one half of
a balanced amplifier fails, it will still operate with a gain reduction of about 6 dB.
