Utilizing highly linear Class AB LDMOS semiconductor technology, Coaxial Packaged Bi-Directional Amplifiers include 2 narrow band models that operate in L-Band from 1.35–1.39 GHz and S-Band from 2.4–2.5 GHz. General purpose broadband model covers 30 MHz to 3 GHz and uses Class A GaAs semiconductors. Typical gain levels range from 20–23 dB with ±0.5 dB gain flatness. Providing 1 µs switching, amplifiers are suited for UAV, military radio, air traffic control, and weather observation.
