Acorde Technologies ACLNBD-Ka Dual-Band Series Ka LNB
Input frequency from 19.2 to 21.2 GHz, Super Low Spurious Emisions, Gain: 60 dB
ACLNBD-Ka Dual Frequency Band LNB
Acorde Technologies Corp Ka-Band Dual Frequency Low Noise Block Downconverters are highly engineered to deliver outstanding RF Receive performance from 19.2 to 21.2 GHz in two 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
ACLNBD-Ka LNBs are engineered and designed for use in all commercial earth stations, VSAT Networks and Satcom Communications systems.
RF Performance
ACLNBD-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.
