1, 3, 4, 6, 10, 13, 16, GND Ground Connection (See Figure 3). 19, 24, 27 2 RFIN RF Input. DC couple RFIN and match it to 50 Ω (see Figure 4). 5 RFOUT RF Output. DC couple RFOUT and match it to 50 Ω (see Figure 5). 7 VDET Detector Voltage for the Power Detector (See Figure 6). VDET is the dc voltage representing the RF output power rectified by the diode, which is biased through an external resistor. Refer to the typical application circuit for the required external components (see Figure 38). 8 VREF Reference Voltage for the Power Detector (See Figure 6). VREF is the dc bias of the diode biased through an external resistor used for the temperature compensation of VDET. Refer to the typical application circuit for the required external components (see Figure 38). 9, 12, 15, 18, 25, 26 VDD6 to VDD1 Drain Bias Voltage for the Variable Gain Amplifier (See Figure 7). For the required external components, see Figure 38. 11, 14, 17, 20, 28 VGG6 to VGG3, Gate Bias Voltage for the Variable Gain Amplifier (See Figure 8). For the required external components, VGG1/VGG2 see Figure 38. 21, 22 VCTL2, VCTL1 Gain Control Voltage for the Variable Gain Amplifier (See Figure 9). For the required external components, see Figure 38. 23 ENVDET Envelope Detector (See Figure 10). For the required external components, see Figure 38. Die Bottom GND Ground. Die bottom must be connected to the RF/dc ground (see Figure 3). Rev.
