PRO-QLNA 380-520
High-Performance Quadrature Low Noise Amplifier / Preamplifier for 380 - 520 MHz
Description
- Mast mounted or wall mounted LNA suitable for:
- Mast head amplifier to compensate for high cable loss.
- Preamplifier in antenna signal distribution network.
- Ensures low system noise figure in receiver systems.
- Built-in low-loss input preselector prevents amplifier overload from e.g. nearby transmitters in adjacent frequency bands:
- Rejects the entire HF/VHF range 0 to 240 MHz > 30 dB.
- Rejects LTE, GSM and UMTS > 30 dB.
- LNA design with two identical amplifier stages coupled in quadrature ensures high reliability. If a fault occurs in one amplifier stage, the LNA will continue to operate with only minor performance deterioration.
- Very high OIP3.
- Low input and output VSWR ensure excellent matching to other units.
- Low weight.
- Wide temperature range.
- Wide supply voltage range.
- Low power consumption.
- DC supply from phantom voltage on the output cable, e.g. by means of junction box PRO-JB1-1G.
- UV-resistant ABS box with water drip.
- N-female connectors on input and output.
