The Q/V-Band Low Noise Block (LNB) from Swedish Microwave converts input frequencies from 37.50 – 42.50 GHz to output frequencies from 950 – 3450 MHz. It has an LO frequency from 36.55 to 40.55 GHz with an LO leakage of less than -60 dBm. This LNB provides a programmable gain from 40 to 55 dB with automatic temperature gain compensation and an image rejection of more than 23 dB. It has a phase noise of -93 dBc/Hz (@100 kHz offset), a noise figure of less than 3.4 dB and spurious levels of better than -60 dBc. The LNB features alarm functions for LNA failure, total current, LO lock, signal power (high/low) and low supply voltage. This LNB requires a DC supply from 11 to 26 V and consumes less than 5 W of power.
The Q/V-Band LNB can be controlled via a MODBUS RTU electrical interface. It is available in a module that measures 144 x 74 x 45 mm with WR22 waveguide input interface and N-type (optional SMA) output connectors.
