The KU BDA 230250–25 A bi-directional amplifier is designed to support various analog and digital modulation types and signal waveforms. The transmitter features LDMOS technology and delivers more than 20 W P1dB power. Switching between transmit and receive path is done automatically depending on the input power level. The receiver’s built-in LNA provides a very low noise figure and additional power gain, which enhances the sensitivity of your receiver.
