The Mini-Circuits ZFL-500HLN+ is a low-noise amplifier engineered for VHF/UHF receiver systems and small-signal applications requiring high gain with minimal noise contribution across a wide frequency band. This 50 Ω coaxial amplifier delivers 19 dB typical gain with exceptional flatness and a 3.8 dB noise figure, making it ideal for sensitive detection circuits and communications infrastructure.

– Key Features
• Tight gain flatness of ±0.4 dB across the entire frequency band ensures predictable system response
• Low 3.8 dB noise figure minimizes cascade noise in multi-stage receiver chains
• IP3 of +30 dBm provides good third-order distortion performance for crowded RF environments
• SMA connectors support flexible integration in standard 50 Ω systems
• RoHS compliant design meets current environmental regulations
• Compact Y460 package measures 2.18″ × 1.688″ (55.37 mm × 42.88 mm) with 38 gram weight
– Typical Applications
• VHF/UHF receiver front ends
• Instrumentation and test equipment signal conditioning
• RF communications systems
• Small-signal amplification in lab and field environments
– Compatibility & Integration
The device operates within standard 50 Ω transmission line systems using SMA connectors. Nominal 15 V single-supply operation requires ≤110 mA current. Derating applies: when driving open-load conditions, reduce maximum input power by 20 dB from the +15 dBm specification.
