  • Downloads

L-band amplifier with adjustable Gain and high output level (P1dB=+20dBm) is intended for compensation of signal loss at long coaxial connections or boosting a weak L-band signal from passive dividers/combiners. Main features of this devices are adjustable Gain (-10...+20dB), easy access to controlling buttons, saving case hermetization and high Gain linearity at full frequency band at any Gain level. Also L-band amplifier has DC and 10MHz bypass, DC supply by coaxial cable.
