Low Noise AmplifiersPRO-LNA-350-520-...

Band selective High-Performance Low Noise Amplifier / Preamplifier for the 350 - 520 MHz band with built-in low-loss preselector

Description

Covers the whole frequency range from 350 - 520 MHz.
Built-in low-loss input preselector. Prevents amplifier overload from e.g. nearby transmitters in adjacent frequency bands:
- Rejects the entire HF/VHF range from 0 to 240 MHz > 30 dB
- Rejects LTE, GSM and UMTS > 30 dB
Miniature LNA suitable for:
- Preamplifier in receiver systems to ensure low system noise figure.
- Preamplifier in antenna signal distribution network.
- Compensating for high cable loss.
Very low noise figure ensures best possible S/N ratio of weak RF signals.
Excellent amplifier dynamic range ensure handling of strong RF signals with very low level of IM distortion.
Low input and output VSWR ensure excellent termination of connected units (e.g. filters).
Low power consumption.
Built-in voltage regulator ensures wide supply voltage range.
DC supply on solder terminal or on 2.5 mm barrel DC connector.
DC supply from phantom voltage on the output cable available as option (-PHDC).
Available with N(f), SMA(f) or TNC(f) connectors.
Low weight.
Wide temperature range.
Sturdy aluminium box.
This filter is coated with black vinyl to prevent corrosion.
