Hartwig- RF Invents a new masthead preamplifier! Thispreamplifier was desingned for Ham Radio Operators, Astronomy,
EMC, ADS-Bor to boost sensitivity of SDR - Systems and Scanners!
Ourpreamplifer operates between 25 MHz and 3000 MHz but best data for
noise figure and gain are beeing achieved above 40 MHz up to 1600MHz,
compare our data with competitors, we clearly outperform all!
On request we can modify this preamp with high- or lowpass filters to get
a higher dynamic range. This will help for example to block out low VHF
< 80 MHz when monitoring FM - Radio stations by their RDS - code on Meteor
Scatter!!
This preamplifier may be fed with 12 - 15 Volt / DC @ 90 mA through an external cable or through the
coax - cable running down into the house but you than need a BIAS - T at the receiver end to feed voltage
up the cable!!On request we offer a decent BIAS - T with flat frequency respone up to 3 GHz, handling 12 V / 1 A.
Connectors are N - female but can be changed to SMA - female. Please just ask!
Youneed a low noise preamplifier in the lab to get a more sensitiv
spectrum – analyzer, therefor we offer some different designs
andeven a kit for skilled technicans! Take a look at our other
listingsplease!
