5.2 Input /Output Matching and Filtering

The CC2592 includes a balun and a matching network in addition to the PA, LNA and RF switches which makes the interface to the CC2530 seamless.

Note that the PCB lines that connect the two devices also are part of the RF matching. Copy the distance between the devices, the transmission lines, and the stack-up of the PCB according to the reference design to ensure optimum performance. The network between the CC2592 and the antenna (C3101, L3101, C3106, L3102, C3103, L3104, C3105 and C3110) matches the CC2592 to a 50 Ω load and provides filtering to pass regulatory demands. C3110 also works as a DC-block. Note: component names in Figure 8 may be different from the design files in the ZigBee CC2530 Wireless MCU and CC2592 Range Extender Reference Design.
