7.3.1 Single-Supply Operation

The TRF1108 supports single 5V supply operation for ac-coupled applications. Supply decoupling is critical to high-frequency performance. Typically, two or three capacitors are used for VDD supply decoupling. Use a 220nF, small-form-factor, 0201-size component placed closest to the VDD pin of the device. Use 0402-size, 2.2μF bulk decoupling capacitors placed next to the small capacitor. A ferrite bead can be further used to filter power-supply noise. For single-supply operation, short VSS to RF ground. Additional layout recommendations are given in Section 7.4.
