Transceiver completes links for military and satcom

Narda, an L-3 Communications company, has introduced the Model 15172 transceiver that aims to provide a compact, cost-effective solution for interfacing systems that employ a 70-MHz intermediate frequency (IF) to single-band, tri-band, or quad-band block converters in military satellite communications systems.

The Model 15172 upconverts or downconverts signals between the 70-MHz IF and the entire band from 950 MHz to 2 GHz. The output frequency can be set at any point within the band with step sizes as small as 20 kHz and as broad as 1 MHz.

The Model 15172 features phase noise performance that exceeds the requirements of MIL-STD-188-165A, the military standard that establishes mandatory requirements for frequency-division multiple access (FDMA) modems employed in satellite communications Earth terminals. Measuring 6 x 8 x 1.5 in., the transceiver weighs 4 lb., making it well suited for integration into rack drawers and other space-critical enclosures.

RF output power at 1-dB gain compression of the upconverter section is typically at least +15 dB with variation of no more than +/-0.15 dB over a 24-hr. period. Noise figure of both the upconverter and downconverter is 16 dB or less and return loss is at least 15 dB. Transfer gain of the upconverter is 25 dB and 40 dB for the downconverter, both controllable in 0.25-dB steps. They will accept an input signal from 52 to 88 MHz at typical of levels of -29 to 0 dBm. Operating temperature range is -20 +70deg C.
