The Netcom’s Line Replaceable Unit (LRU ) filter line covers the frequency range of 1.5MHz to 90MHz. The LRU filters are self-contained modular component filters designed to be installed and replaced quickly within a system without the use of specialized tools. The power range of the LRU line of digitally tunable filters range from 0.25 watts to 48 watts.
The single and multi-band LRU filters help to reduce the reverse inter-modulation products and harmonics synchronously with the selected “hop” et as commanded by the host radio. The LRU filters operate both in transmit and receive path of the system and are often placed right after the antenna input/output.
