Acorde Technologies ACLNBS-Ka Standard Series Ka-Band LNB
Input frequency from 18.3 to 21.2 GHz, Super Low Spurious Emisions, Gain: 60 dB
ACLNBS-Ka LNB
Acorde Technologies Corp Ka-Band Low Noise Block Downconverters are highly engineered to deliver outstanding RF Receive performance from 18.3 to 21.2 GHz in three different sub frequency bands. These Ka LNBs offer excellent spurious performance throughout the entire frequency range, while delivering reliable operation even in 100% humidity. RF Input is accomplished via a grooved WR28 precision flange.
Versatile
ACLNBS-Ka LNBs are engineered and designed for use in all commercial earth stations, VSAT Networks and Satcom Communications systems.
RF Performance
ACLNBS-Ka Standard Series have been designed to meet restrictive specifications for Ka Band communication systems. The equipment has a typical gain of 60 dB with a Noise Figure lower than 1.5 dB typically, with low weight and dimensions.
