RETURN LOSS AND ISOLATION

IF and I/Q amplitude = −20 dBm, VCC_DRV = VCC2_DRV = VCC_AMP2 = VCC_ENV = VCC_AMP1 = VCC_BG2 = VCC_MIXER =

VCC_BG = VCC_QUAD = 3.3 V, DVDD = VCC_VVA = 1.8 V, TA = 25°C, and set Register 0x0A to 0xE700, unless otherwise noted.

Measurements in IF mode performed with a 90° hybrid, Register 0x03, Bit 7 = 1, and fIF = 3.5 GHz.

Measurements in I/Q mode are measured as a composite of the I and Q channel performance, VCM = 0 V, Register 0x03, Bit 7 = 0, and

VCTRL1 = VCTRL2. VCTRL is the attenuation voltage at the VCTRL1 and VCTRL2 pins. VCTRL = 1800 mV, unless otherwise specified.

Envelope detector measurements made with Register 0x03, Bit 5 = 1.
