The inductors used in Silicon Labs reference designs are currently wire-wound surface mount inductors, such as the Murata LQW15Aor LQW18A series, or the CoilCraft 0402CS, 0402HP, 0603CS, or 0603HP series. Wire-wound inductors provide the best performance,but are more expensive. It is possible to use a cheaper series of inductors (i.e., multi-layer inductors such as the Murata LQG15HSseries), however, there will be some slight increase in insertion loss that will result in a decrease in TX output power and/or a degradationin RX sensitivity. This degradation in performance is small, typically less than 0.5 dB.
