KU PA 070080-20 A, RF Power Amplifier
770 ... 880 MHz • 20 W
The power amplifier is developed both for digital and analog transmission systems. It's frequency range is chosen to cover the new UHF frequencies for the cellular phone network completely. By the use of LD-MOSFET-technology high efficiency and low current consumption are reached at the same time.
