DN003 -- Implementation of Microstrip Balun for CC2420 and CC243x and CC2480 (Rev. D)

This design note shows how to implement a microstrip balun design for the CC2420, CC243x and CC2480 devices. The design is needed to transform the two differential TX outputs into a single ended signal in TX mode and to split the single ended antenna signal into a differential RF signal in RX-mode. This helps reducing the number of parts on the BOM (bill of material).
