1pc SPF5189 / SPF5189Z (SPF5189Z) RF Low Noise Amplifier (LNA) with Shielding Shell Frequency range: 50–4000 MHz | Noise Figure: 0.6 dB Why you need it Significantly improves weaksignal reception by lowering system noise floor with a very low noise figure (NF = 0.6 dB). The integrated shielding shell reduces interference and prevents coupling from nearby components, delivering cleaner amplification in crowded RF environments. Wide 50–4000 MHz bandwidth makes it a versatile frontend option for many RF receiver designs, avoiding the need for multiple bandspecific amplifiers. Key benefits Better signaltonoise ratio: 0.6 dB NF helps recover faint signals and improves overall receive sensitivity. Broad compatibility: One module supports VHF, UHF, cellular, satellite bands and many other RF services within 50–4000 MHz. Cleaner system performance: Metal shielding shell provides effective EMI/RFI protection for reliable operation in mixedsignal setups. Easy integration: Compact LNA module designed for implementation in RF frontends, test rigs, and communication devices. Features and attributes Model: SPF5189 / SPF5189Z (SPF5189Z) Type: RF Low Noise Amplifier (LNA) / RF signal receiver frontend Frequency range: 50–4000 MHz (broadband) Noise figure: 0.6 dB (typical) Enclosure: Shielding shell (metal) for reduced interference and improved stability Quantity: 1 piece (1pc) Compatibility and use Designed for integration into RF receiver chains, softwaredefined radio (SDR) setups, test and measurement equipment, and custom RF modules. Works with a wide range of antenna systems and receivers that operate within the 50–4000 MHz range. Typical applications SDR and amateur radio: Use as a frontend LNA to enhance reception of weak HF/VHF/UHF signals and improve demodulation performance. TV, satellite and terrestrial receivers: Improve sensitivity for overtheair TV, satellite downlinks and other broadcast services. Wireless infrastructure and test equipment: Ideal for prototypes and lab setups that require a lownoise, broadband amplifier with shielding to reduce interference. Notes for integrators Intended as an RF frontend amplifier module; observe standard RF layout and grounding practices when integrating to preserve lownoise performance. Confirm mechanical and connector compatibility with your system before installation. This singlepiece SPF5189/SPF5189Z LNA delivers broadband lownoise amplification with a shielding shell to improve realworld receiver performance across 50–4000 MHz.
