Mini-circuits ZFL-1000

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

• Frequency Range: 0.1 MHz to 1000 MHz
• Gain: 20 dB typical; Gain Flatness ±0.5 dB across operating range
• Output Power (1 dB Compression): +3 dBm typical
• Noise Figure: 2.9 dB (ZFL-1000LN+) / 4.5 dB (ZFL-1000VH)
• Third Order Intercept Point (IP3): +14 dBm (ZFL-1000LN+) / +38 dBm (ZFL-1000VH)
• Input/Output VSWR: 1.5:1 input / 2.0:1 output typical; ZFL-1000VH input VSWR reaches 2.25:1 max below 20 MHz
• Impedance: 50 Ω
• Supply Voltage: 15 V nominal (17 V max)
• 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.
