The Nooelec LaNA is a wideband low-noise amplifier used with SDR systems. Here are the key specifications in a clear summary:
📡 Nooelec LaNA (Wideband version) specifications
Frequency range
- ~20 MHz to 4 GHz (wideband SDR use)
Gain (typical, frequency dependent)
- ~26 dB @ 50 MHz
- ~24 dB @ 100–500 MHz
- ~20 dB @ 1 GHz
- ~17 dB @ 1.5 GHz
- ~16 dB @ 2 GHz
Noise performance
- Low-noise design (exact noise figure varies with frequency; manufacturer provides curves in datasheet rather than a single fixed NF value)
Power requirements
- 3.3–5.5 V DC typical operation
- Current consumption: ~50–80 mA
Power options (3 methods)
- Bias-T via SDR (3–5 V)
- Micro-USB power input
- DC barrel jack
RF handling
- Max recommended input: about 0 dBm (1 mW)
- Absolute survival higher in some cases, but not recommended beyond spec
Output power (if misused as TX amp)
- Up to ~20 dBm (~100 mW), but not designed for transmission use
Physical / build
- Shielded aluminum enclosure
- ESD protection built in
- SMA connectors (male SMA in standard kit)
⚙️ Practical notes (important in real SDR setups)
- Best used at the antenna end of a long coax run (not at the SDR if signal is already strong).
- Can easily cause overload in strong-signal environments (FM broadcast, paging transmitters).
- Often performs better with band-pass or notch filtering ahead of it depending on band.
