3 Architecture  
The TRC104 is a single-chip FSK transceiver that operates in the worldwide 2.4 GHz ISM band. The TRC104s  
highly integrated architecture requires a minimum of external components. Advanced features including the  
TX/RX FIFO and the burst packet data mode significantly reduce the TRC104s load on the host microcontroller.  
As shown in Figure 2, the TRC104 utilizes a dual-conversion superheterodyne receiver architecture with an  
image-reject second mixer. The VCO operates directly at the output frequency when transmitting, and is  
modulated by a Gaussian-filtered bit stream.

3.1 RF Port  
The TRC104 has a differential RF port that is capable of delivering the required transmitter output power at low  
supply voltages. The differential RF port also provides common mode signal rejection to enhance receiver  
interference immunity. A simple L-C balun can be used to convert the differential port to a single-ended output to  
drive an unbalanced antenna, as shown in Figure 3.  
3.2 Transmitter Power Amplifier  
The power amplifier controls the output power level of the transmitter. The power amplifier has four programmable  
power levels. The power level is set by the PWR bits in configuration register 0x01.
