The Mini-Circuits ZFL-1000 is a wideband RF small-signal amplifier engineered for test, measurement, communications, and radar applications. Operating from 0.1 MHz to 1000 MHz with 20 dB typical gain and ±0.5 dB gain flatness, this 50 Ω amplifier delivers consistent performance across DC to microwave frequencies. The ZFL-1000 family includes noise-optimized (ZFL-1000LN+) and high-linearity (ZFL-1000VH) variants, enabling selection based on system requirements for either low-noise reception or high-power handling.
Technical Specifications

• Operating Temperature: −20°C to +71°C
• Storage Temperature: −55°C to +100°C
– Key Features
• Flat gain response enables direct integration into wideband signal chains without equalization
• Model variants optimize for noise figure (LN+) or linearity (VH) depending on application demands
• Coaxial package with SMA connectors (ZFL-1000+) simplifies board-level and test-bench integration
• Low input VSWR supports low-loss matching networks
– Typical Applications
• Cellular and VHF/UHF receiver front-ends
• Radar signal detection and processing
• Test equipment and instrumentation amplification
• Small-signal chain gain blocks
– Compatibility & Integration
The ZFL-1000 operates on single +15 V supplies with minimal current draw. Coaxial package variants (SS98, Y39, Y460) accommodate different mechanical mounting requirements. For ZFL-1000VH units, derate maximum input power 20 dB under no-load conditions; open-load operation is not recommended.
