This high linear Low Noise Amplifier was developed for applications in the VHF range where high intermodulation distortion ratio and high input sensitivity are required. This LNA is balanced with two hybrid couplers which guarantee excellent input SWR and linearity. It can be supplied with DC voltage via the coaxial cable (remote power supply) or directly (solder pin).
