Pin Function Description Interface Schematic 1G N D Ground connection. 2G N D Ground connection. 3G N D Ground connection. 4R F I N RF input. An external 100pF series capacitor is required as a DC block. In addition, shunt inductor and series capacitor are required to provide 2:1VSWR. 5V R E G 1 Power Down control for first stage. Regulated voltage supply for ampli- fier bias. In Power Down mode, both V REG and VMODE need to be LOW (<0.5V). 6V M O D E For nominal operation (High Power Mode), VMODE is set LOW. When set HIGH, the driver and final stage are dynamically scaled to reduce the device size and as a result to reduce the idle current. 7V R E G 2 Power Down control for the second stage. Regulated voltage supply for amplifier bias. In Power Down mode, both V REG and VMODE need to be LOW (<0.5V). 8B I A S G N D Bias circuitry ground. See application schematic. 9G N D Ground connection. 10 RF OUT RF output and power supply for final stage. This is the unmatched col- lector output of the second stage. A DC block is required following the matching components. The biasing may be provided via a parallel L-C set for resonance at the operating frequency of 824MHz to 849MHz. It is important to select an inductor with very low DC resistance with a 1A current rating. Alternatively, shunt microstrip techniques are also appli- cable and provide very low DC resistance. Low frequency bypassing is required for stability. 11 RF OUT Same as pin 10. See pin 10. 12 RF OUT Same as pin 10. 13 2FO Harmonic trap. This pin connects to the RF output but is used for pro- viding a low impedance to the second harmonic of the operating fre- quency. An inductor or transmission line resonating with an on chip capacitor at 2fo is required at this pin. 14 VCC BIAS Power supply for bias circuitry. A 100pF high frequency bypass capaci- tor is recommended. 15 VCC1 Power supply for first stage. 16 VCC1 Same as Pin 15. Pkg Base GND Ground connection. The backside of the package should be soldered to a top side ground pad which is connected to the ground plane with mul- tiple vias. The pad should have a short thermal path to the ground plane.
