RF3300-3 0 Typical Applications * 3V CDMA US-PCS Handsets * 3V CDMA2000/1X PCS Handsets * Spread-Spectrum Systems Product Description The RF3300-3 is a high-power, high-efficiency linear amplifier IC targeting 3V handheld systems. The device is manufactured on an advanced Gallium Arsenide Heterojunction Bipolar Transistor (HBT) process, and has been designed for use as the final RF amplifier in dual-mode 3V CDMA handheld digital cellular equipment, spreadspectrum systems, and other applications in the 1850MHz to 1910MHz band. The RF3300-3 has a digital control line for low power application to reduce the current drain. The device is self-contained with 50 input and output that is matched to obtain optimum power, efficiency, and linearity characteristics. This amplifier contains a temperature compensating bias circuit for improved performance over temperature. 7.375 TYP 6.775 6.575 TYP 5.875 TYP 3V 1900MHz LINEAR AMPLIFIER MODULE * Designed for Compatibility with Qualcomm Chipsets 1.625 2.425 3.575 4.375 1 5.075 TYP 4.375 TYP NOTES: Nominal thickness, 1.55 mm.

A low frequency decoupling capacitor (2.2F) is required. Type: P Ground connection. Connect to the GND_SLUG pin. For best performance, keep traces physically short and connect immediately to ground plane. Type: P Ground connection. Connect to the GND_SLUG pin. For best performance, keep traces physically short and connect immediately to ground plane. Type: P RF input internally matched to 50. This input is internally AC-coupled at the IC; however a shunt inductor used in the input matching network will provide a DC path to ground for components connected to the RF IN pin. A DC blocking capacitor may be required at this pin. Type: A, I Interface Schematic VCC1 RF IN From Bias Stage 5 6 7 8 9 10 11 VCC1 GND GND RF OUT VCC2 PDET_OUT VMODE First stage power supply.

Type: A, O Output stage power supply. A low frequency decoupling capacitor (2.2F) is required. Type: P Power detector output. Type: A, O Gain step control. When this pin is High, the module is in low power mode, and the amplifier's current is reduced. When this pin is Low, the module is in high power mode. Voltage should not be applied to this pin before VCC3 is applied. Type: D, I Device enable control. When this pin is High, the device is on. When this pin is Low, the device is off. Voltage should not be applied to this pin before VCC3 is applied. Type: D, I Ground connection. The backside of the package should be soldered to a top side ground pad which is connected to the ground plane with multiple vias. The pad should have a short thermal path to the ground plane.
