The Texas Instruments (TITM) TRF1015 is a single-chip RF downconverter suitable for 900-MHz receiver applications. It combines a low-noise amplifier (LNA), a buffered voltage-controlled oscillator (VCO), and an RF mixer into a 20-pin SSOP package requiring very few external components. Minimal power consumption can be further reduced by placing the required modules into operate mode and the remaining modules into standby mode. Three modes of operation are provided for both the LNA and the mixer: standby, low current, and improved compression. The improved compression mode is suitable for applications that require full duplex capability. The improved compression mode is suitable for maintaining receiver sensitivity in the presence of large interfering signals and provides a low bit-error rate (BER) in digital modulation systems. The three modes of operation are selectable in accordance with the presence of a high or low signal on PD1 and PD2, as shown in Table 1.
