| RF2367 0 RoHS Compliant & Pb-Free Product Typical Applications * TDMA/CDMA/FM PCS Tx Amplifier * Low Noise Transmit Driver Amplifier * 2.4GHz WLAN Systems Product Description The RF2367 is a low noise CDMA/TDMA/GSM PA driver amplifier with a very high dynamic range designed for transmit digital PCS applications with frequency ranges between 1700MHz and 2000MHz. The device functions as an outstanding PA driver amplifier in the transmit chain of digital subscriber units where low transmit noise power is a concern. The IC includes a power down feature that can be used to completely turn off the device. The RF2367 is featured in a standard SOT23-6 plastic package. 1.80 1.40 0.50 0.35 0.10 MAX.

Keep traces physically short and connect immediately to ground plane for best performance. Same as pin 1. RF input pin. This pin is DC coupled and internally matched to a <2:1 VSWR at 1880MHz. PD Interface Schematic RF IN TO OUTPUT STAGE 4 PD 5 6 GND RF OUT See pin 3. Power Down for the IC. VPD = 2.8V +/- 0.1V turns on the Part. VPD <0.9V turns off the Part. Lower threshold for device operation is approximately 1.2V. External RF bypassing is required. The trace length between the pin and the bypass capacitors should be minimized. The ground side of the bypass capacitors should connect immediately to ground plane. Nominal current for this pin for VPD = 2.8V is 8mA typical. Same as pin 1. Amplifier Output pin. This pin is an open-collector output. It must be biased to either VCC or pin 4 through a choke or matching inductor. This pin is typically externally matched to 50 with a shunt bias/matching inductor and series blocking/matching capacitor. Refer to application/evaluation board schematics.
