This high linear preamplifier was developed for applications in VHF communication band. It is suitable especially for applications where a high intermodulation distortion ratio and at the same time a high input sensitivity are used. The coupling happened through 3dB hybrids, which guarantee an excellent input SWR and linearity of the preamplifier. The voltage supply via coax cable (remote power supply) or direct at the case is possible.
