TTI-LNB-KA-1921-A Image

The TTI-LNB-KA-1921-A from TTi is a Low Noise Block (LNB) that converts an input frequency of 19.2 – 21.2 GHz (Ka-Band) to an output frequency from 1 – 2 GHz (L-Band). It has an 18.2/19.2 GHz local oscillator. This LNB provides a gain of 60 dB and has a noise figure of less than 1.5 dB. It has spurious levels of -60 dBc (@P1dB) and a VSWR of less than 1.6:1. The LNB requires a DC supply from 12 to 28 V and consumes less than 250 mA of current. It is available in a module that measures 105 x 44 x 40 mm with WR-42 input interface and N-type (female) output connector. This LNB is ideal for satellite signal conversion applications.
