The high linear preamplifier KU LNA BB2240 A is designed for the UHF communications band. It features best large signal performance and a low noise figure. Internally it uses 3dB hybrids for input and output coupling. This leads to good input return loss, output return loss and high third order intercept point (IP3). The preamplifier contains a bias-T for remote power supply via coaxial cable and a solder pin for direct power supply.
