On sale On sale!
£6.45 incl. tax

Here we have an in-line LNA built on the Mini-Circuits PSA4-5043+ Ultra Low noise (0.7 to 1.44 db) MMIC amplifier. It can be powered by a DC supply of 3 - 15v and has been designed to provide a boost of roughly 17-19 db. It can be used in portable radio receivers to give a DX functionality and it works well from 1 MHz to 2.5 GHz

 

 

You will need to have some basic knowledge of electronics and some soldering skills in order to set it up.

Set the dongle to auto gain (Gain -10 if using dump 1090) running off 5 volt seems to give just the right ammount of extra gain without too much noise. Interestingly Fully RF shielding these had no impact on performance, so i wouldnt be too fussy with the housing unless its in a RF noisey enviroment.

04/2/2016 jeff f. poor quality soldering i have purchased 3 of these amps 2 have not worked due to a poor solder joint on the inductor i resoldered them but it is not easy and one was ok but the other destroyed its self after applying 15v so...i fitted a 100ohm resistor to the other 2

Apologies for the trouble you have had with them. We will make sure similar things do not happen in the future. The 15V top voltage mark on the PCB is an absolute maximum and even a slight spike above that will fry the regulator. You should always try and contact customer services first for a possible solution.

Best regards,

CONTAGIOUS CANCER DISCOVERED

"Scientists have discovered the first contagious type of cancer that seems to jump between animal species, and they suggest that cancers that spread like viruses could be more widespread than we thought.

Eight different types of contagious cancer have now been identified. We've known about one type in dogs and two types in Tasmanian devils for several years now, but a new study has identified five more types of contagious cancer in four species of molluscs and their close relatives." - www.sciencealert.com
