SVP AEROSPACE LNA-2GHz Low Noise Amplifier Instruction Manual
Dear Customer,
We would like to thank you for choosing this equipment and welcome you to the
SVP’s growing family of products.
We are sure that the addition of this equipment to your existing installation will cause you nothing but satisfaction.
Please read these instructions carefully, and keep them at hand in case you have to refer to them.
IMPORTANT NOTES:
- The LNA low noise preamplifier for COFDM signals has a selective input filter, which can be modified under request of the customer in order to work in the wanted frequency range.
- The COFDM low noise preamplifier is powered through the output coax connector. For it, a bias insertion tee (BIAS-TEE) can be used, which is an accessory available in our catalogue.
- The high performance of this equipment is only guaranteed using high quality cables and connectors.
1. Description
The very low noise preamplifier for COFDM signals offers its best performance with COFDM digital links. Also, it can be used with analogue links. This LNA is very useful for Broadcast applications and air links.
This equipment expands the possibilities of existing COFDM digital links, because with it, the noise figure of the receivers is improved. The selectivity is also increased and it compensates the attenuation caused by the coaxial cable between the antenna and the receiver.
It has two radiofrequency filters: one selective at the input with 5 poles, which enables it to work in the most adverse radiofrequency environments and other between the amplifier’s stages.
The COFDM low noise preamplifier uses PHEMT technology and 90º hybrid couplers to ensure excellent linearity. The third order intermodulation products (IP3) are +33 dBm, which means they have no problem working with strong COFDM signals modulated in 64QAM.
The LNA preamplifier for COFDM signals has an excellent noise figure and so, link sensitivity is increased, thus improving coverage and reliability.
It has a good input adaptation, eliminating undesired self-oscillations.
The LNA is powered through the output coax. For it, a bias insertion tee
(BIAS-TEE) can be used.
