42-57D-05 Series

42-57D-05 Series, 380-512 MHz, Receiver Multicouplers provide unequaled performance in a 1-rack unit (1-3/4 inch) space-saving package. The high performance LNA ’s exhibit a very low noise figure while providing a (100% measured) 3rd order output intercept point in excess of +40 dBm. The multicouplers are designed with a minimum gain of 12 dB which gives maximum sensitivity in rural applications. All the units are designed for ease of expansion, with no change in system gain in most cases. Three basic models cover the most popular applications from 118 - 901 MHz.
