PACKAGE PIN OUT 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 LQ PACKAGE (Bottom View) RoHS / Pb-free 100% Matte Tin Lead Finish FUNCTIONAL PIN DESCRIPTION Pin Name Pin Number Description RF IN 2, 3 RF input for the power amplifier. This pin is DC-shorted to GND but AC-coupled to the transistor base of the first stage. For 5.15-5.35GHz this pin is pre-matched to 50 Ω. Vb1 6 Bias current control voltage for the first stage. Vb2 7 Bias current control voltage for the second stage. The VB2 pin can be connected with the first stage control voltage (VB1) into a single reference voltage (referred to as Vref) through an external resistor bridge(R1/R2). Vcc 9 Supply voltage for the bias reference and control circuits. The VCC feed line should be terminated with a 1 μF bypass capacitor as close to the device as possible. This pin can be combined with both VC1 and VC2 pins, resulting in a single supply voltage (referred to as Vc). RF OUT 10, 11 RF output for the power amplifier. This pin is AC-coupled and does not require a DC-blocking capacitor. Vc1 15 Power supply for first stage amplifier. The VC1 feedline should be terminated with a 220pF bypass capacitor as close to the device as possible, followed by a 1 μF bypass capacitor at the supply side. This pin can be combined with VC2 and VCC pins, resulting in a single supply voltage (referred to as Vc). Vc2 14 Power supply for second stage amplifier. The VC2 feedline should be terminated with a 220pF bypass capacitor as close to the device as possible, followed by a 1 μF bypass capacitor at the supply side. This pin can be combined with VC1 and VCC pins, resulting in a single supply voltage (referred to as Vc). GND The center metal base of the MLP package provides both DC and RF ground as well as heat sink for the power amplifier. |
