RETURN LOSS AND ISOLATIONS

RF amplitude = −30 dBm, measurements performed with a 0 mV dc bias. VCC_MIXER = VCC_QUAD = VCC_BG = VCC_LNA =

VCC_VGA = VCC_IF_BB = 3.3 V, DVDD = VCC_VVA = 1.8 V, Register 0x0B is set to 0x727C, Register 0x03, Bits[13:12] are set to 11,

Measurements in IF mode performed with a 90° hybrid, Register 0x03, Bit 11 = 0, Register 0x03, Bit 8 = 1, unless otherwise noted.

Register 0x03, Bit 8 = 0, unless otherwise noted.
