POWER SUPPLIES Voltage Supply VDD 3.1 3.3 3.6 V Main supply input VSUP1 2.6 V Output from internal LDO1, 10 mA rating, supply for RX VCO VSUP2 2.8 V Output from Internal LDO2, 30 mA rating, supply for RX baseband and RX down- converter VSUP3 1.9 V Output from internal LDO3, 10 mA rating, supply for RX LNAs VSUP4 2.6 V Output from internal LDO4, 10 mA rating, supply for TX VCO VSUP5 2.8 V Output from internal LDO5, 100 mA rating, supply for TX modulator, TX baseband, PA control DACs VSUP6 1.9 V Supply input for RX synthesizer, connect to VSUP3 VSUP7 1.9 V Supply input for TX synthesizer, connect to VSUP3 VSUP8 2.8 V Supply input for reference section, connect to VSUP2 VINT 1.6 1.8 2.0 V Supply input for serial interface control logic CURRENT CONSUMPTION Transmit Current Consumption VDD = 3.6 V, output is matched into 50 Ω −8 dBm Output Level 100 mA FRF = 2170 MHz −28 dBm Output Level 50 mA FRF = 2170 MHz Receive Current Consumption 50 mA 1 The reference frequency should be dc coupled to the REFIN pin. It is ac-coupled internally. 2 The noise figure measurement does not include spurious noise due to harmonics of the 26 MHz reference frequency. Spurs appear at integer multiples of the reference frequency (every 26 MHz), degrading the receive sensitivity by about 6 dB. 3 Guaranteed by design, not production tested. 4 Bit sif_vsup8 in Register 2 controls whether 1.8 V readback mode or 2.8 V readback mode is selected. See the Serial Port Interface (S sect PI) ion for more details. Rev.
