Low-Noise Preamplifiers for Maximum Reception Quality and System Performance
Preamplifiers are a key factor in the performance of modern receiving systems. They are installed as close as possible to the antenna in order to amplify weak wanted signals at an early stage and effectively reduce the system noise contribution of the subsequent receive chain. Especially with long feeder cables, high frequencies, or extremely low signal levels, the noise figure, large-signal handling capability, and stability of the preamplifier have a decisive impact on overall system performance.
The SSB-Electronic product range includes high-quality, low-noise preamplifiers with and without transmit/receive switching, dual-band preamplifiers, broadband preamplifiers, and preamplifiers for special frequency ranges, all specifically designed for demanding RF receiving systems. Our units are characterized by a low noise figure, high large-signal robustness, and robust RF impedance matching. Typical applications range from amateur and professional radio systems to antenna and diversity systems, as well as measurement and test environments.
Whether you are looking to improve reception sensitivity, compensate for cable losses, or relieve the input stages of sensitive measurement equipment, our preamplifiers are field-proven and designed for stable performance in real-world RF operation. For special requirements - such as specific frequency ranges, tailored amplifier parameters, or customized mechanical designs - our team will be happy to provide individual technical advice. Please contact us.
Preamplifiers without RX/TX switch
Preamplifiers without transmit/receive switching are specifically designed for receive-only applications and operate exclusively in the receive path. They amplify weak RF signals directly at the antenna, improve the overall noise figure of the receiving chain, and compensate for cable losses. Choose between the following connection standards: N-female, N-male (for direct connection to relays, etc.), or SMA:
- LNA preamplifier in NM version (all bands): an N-male connector is located on the antenna side, and an N-female connector is located on the receiver side.
- LNA preamplifier in NF version (all bands): an N-female connector is located on both the antenna and receiver sides.
- LNA preamplifier in SMA version (all bands): an SMA female connector is located on both the antenna and receiver sides.
