7.2.1.1 Design Requirements

Use TRF2001 to extend the communication range and the TX output power in a sub-1GHz system using

CC1314R10 wireless MCU. The design parameters in Table 7-1 are for a transmitter and receiver setup,

operating at 915MHz frequency with an approximately 1:1 VSWR antenna system.

7.2.1.2 Detailed Design Procedure

The TRF2001 has integrated 50Ω matching elements and in a 50Ω matched system, does not require any

external matching components at the TR or ANT pins. Use the CC1314R10 LaunchPad™ design as reference

to design the balun and the matching network interface between the CC1314RF10 and TRF2001 as shown in

Figure 7-2. Add an optional SAW filter, FL4 in Figure 7-2, to filter any spurs from CC1314RF10 from reaching the

TRF2001.
