Wideband Preamplifier 50-3000MHz F-M High IP3

Wideband Preamplifier 50-3000MHz F-M with PGA103+ offers high dynamic range with very low noise figure. Suitable for all applications where low-noise broadband signal amplification is required, like SDR receivers. The preamplifier has good input and output return loss over a broad frequency range. VLNA amplifies extremely weak RF signals across a massive spectrum while adding minimal internal noise. It boosts signals before processing, making it vital for SDR receivers, multi-standard wireless receivers, and wideband communication monitoring.

F-M (Female-Male) refers to a version with a Female “N” connector on the input side, designed to be put in line with a coaxial cable ending with an “N” male connector.

The best position is to put it as close as possible to the antenna.

 

Wideband Preamplifier 50-3000MHz F-M Appearance:

 

Applications:

• Software-Defined Radio (SDR): Enhances weak antenna signals across VHF and UHF bands without drowning them in amplifier noise.
• Spectrum Monitoring & Defense: Broadens frequency coverage for electromagnetic surveillance and threat detection.
• Telecommunications: Amplifies multi-frequency cellular, Wi-Fi, and intermediate satellite frequencies.
• Test and Measurement: Serves as a front-end gain block for spectrum analyzers and oscilloscopes to measure weak signals accurately.

 

Key Benefits:

• High Sensitivity: Lowers the overall noise figure so weak signals remain clear.
• Wide Coverage: Eliminates the need to swap out band-specific preamplifiers.
• Gain Flatness: Provides even amplification across the entire 50 MHz–3 GHz range.
