KU LNA BB 2533 A
Low Noise Broadband Amplifier
2500 ... 3300 MHz
The preamplifier KU LNA BB 2533 A is designed for radar systems at 2.9 GHz. It features low noise figure, excellent large signal performance and high linearity. Good selectivity is achieved by internal high pass filters. Out-of-band signals are effectively suppressed. This results in a huge range of applications for the preamplifier. Typical applications are radar systems or digital video systems using.
