Distributing one antenna feed across multiple receivers without sensitivity loss
A single high-quality receive antenna feeding multiple receivers — without splitting the signal level so far that sensitivity collapses, and without one receiver loading another.
The naive solution fails
A passive resistive splitter divides power equally — but an 8-way split costs 9 dB, eating most of your link budget. Receivers also load each other's impedance, creating cross-channel desense.
How a multicoupler solves it
Low-noise preamp at the input compensates for the split loss; per-output buffers provide > 20 dB inter-output isolation. Net gain across all outputs is held at 0 ± 6 dB. OIP3 stays high enough that the multicoupler is not the linearity bottleneck for any downstream receiver.
