Product Overview
Mini-Circuits ZFL-1000LN+ (with factory mounting bracket, catalog designation ZFL-1000LNB+) is a 50-ohm coaxial low noise amplifier module covering 100 kHz through 1.0 GHz. Built into a shielded aluminum housing (case style Y460), it delivers 20 dB typical gain and a 2.9 dB typical noise figure across VHF, UHF, and cellular bands. RF connections are made via standard SMA female input and output ports, while DC bias requires a single +15V supply connected to the feedthrough pin and adjacent ground turret.
Key Features
- Frequency range: 0.1 to 1000 MHz
- Gain: 20 dB typical
- Noise figure: 2.9 dB typical
- Output power at 1 dB compression (P1dB): +3 dBm typical
- Output IP3: +14 dBm typical
- Supply voltage: +15V DC at 60 mA typical
- RF impedance: 50 ohms
- Connectors: SMA female input and output
- Housing: Machined aluminum module with integrated four-hole mounting bracket baseplate
Applications
- Front-end receiver preamplification for SDR receivers, spectrum analyzers, and RF field monitors.
- Laboratory bench signal boosting across VHF and UHF test benches without adding significant front-end noise.
- Amateur radio and scanner reception enhancement across HF, VHF, and UHF bands.
Frequently Asked Questions
What DC power connection does this amplifier require?
The module runs on a single +15V DC supply at 60 mA typical. The positive connection solders to the red glass feedthrough pin marked +15V, and the return path connects to the adjacent solder turret terminal marked GND.
What is the difference between ZFL-1000LN+ and ZFL-1000LNB+?
Mini-Circuits uses the B suffix to indicate Option B, which adds the integrated four-hole mounting baseplate bracket to the Y460 housing. The underlying amplifier circuitry, SMA connectors, and RF performance are identical.
What mounting hardware is needed to secure the bracket?
The integral aluminum flange features four pre-drilled through-holes positioned at the corners, sized for standard machine screws onto a chassis or heatsink plate.
Plug this into your front end, dial in fifteen clean volts, and let the quiet boost do the heavy lifting.
