PRO-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.
