NM01PA45dB
This compact and versatile single-channel Radio Frequency (RF) pre-amplifier is specifically designed to amplify weak RF signals within the frequency range of 0.5 MHz to 30 MHz. Featuring an adjustable gain of up to 45 decibels (dB), this unit allows users to precisely boost signal levels to optimize the performance of receivers, spectrum analyzers, and other RF measurement equipment. The adjustable gain control provides the flexibility to enhance the detection of faint signals while minimizing the risk of overdriving subsequent stages.
A key feature of this pre-amplifier is its portability, enabled by its ability to operate on a standard 9-volt battery. This makes it an ideal solution for field applications, remote testing, or situations where access to mains power is limited. The low power consumption design ensures extended operation on a single battery.
For seamless integration into existing RF systems, the pre-amplifier is equipped with industry-standard BNC (Bayonet Neill-Concelman) connectors for both the input and output ports. BNC connectors offer a reliable, shielded connection with a convenient quick connect/disconnect mechanism, ensuring minimal signal loss and interference within the specified frequency range.
This pre-amplifier serves as a crucial building block in enhancing the sensitivity of RF receiving systems, compensating for signal attenuation in cables, and providing a necessary gain stage for accurate measurement and analysis of low-level RF signals across the HF and lower VHF bands. Its ease of use, adjustable gain, battery operation, and standard BNC connectivity make it a valuable tool for engineers, technicians, hobbyists, and anyone working with RF signals in the specified frequency range.
