We would like to give you a snaphot of our Partnes Kuhne electronic’s most recent product developments, in particular:
1) The newest member in our low noise amplifier line KU LNA BB 0012650 A, a broadband pre-amplifier designed for versatile applications from 10 MHz up to 26.5 GHz.
2) We are focusing again on Kuhne’s bidirectional amplifier KU BDA 240250-25A – now also available for licensed band operation with KU BDA 230250-25 A .
3) The GaN HEMT wideband amplifier KU PA 200270-10 A / B based on a strictly modular design, this will be the future platform for other frequency bands.
Enjoy reading and as always, your feedback on our products and services is welcome!
New Low-Noise Broadband and Narrowband RF-Amplifier
The KU LNA BB 0012650 A is Kuhne’s newest low-noise preamplifier and has a bandwidth of 10 MHz to 26.5 GHz and is thus suitable for a variety of applications in the radio-frequency (RF) and microwave range, in particular for the amplification of broadband pulsed signals. Furthermore, the KU LNA BB 0012650 A is characterized by a low noise figure of between 2 dB and 7 dB and a gain of typically 30 dB with a gain flatness of ±2 dB.
- Low noise figure
- High bandwidth
- Good gain flatness
- Reverse polarity and over-voltage protection
Small mechanical dimensions
Bi-Directional Power Amplifier
The KU BDA 240250–25 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.
– No external switching signal necessary
– High operating safety
– Easy monitoring of the operating condition
S-Band Power Amplifier
Based on GaN HEMT technology, the amplifier module achieves energy efficiencies greater than 40% over the entire 2000-2700MHz bandwidth at 10W output power. The amplifier is temperature compensated and, despite its high gain (47dB), features a very low gain ripple of typically +/- 0.75 dB across the full bandwidth.
– Very low ripple, noise figure and good
harmonic rejection over the entire
– Robust I/O interface via Sub-D connector
with monitoring outputs for forward and
reverse power as well as temperature
– Available with wide-range supply voltage
input +10 … 50V (version B)
