| RF2442 HIGH-LINEARITY LOW NOISE AMPLIFIER RoHS Compliant & Pb-Free Product Package Style: MSOP-8 Features Low Noise and High Intercept Point External Bias Control Single 2.5V to 5.0V Power Supply 500MHz to 2500MHz Operation Extremely Small MSOP-8 Package VCC1 1 GND1 2 RF IN 3 GND2 4 8 VCC2 7 NC 6 RF OUT 5 NC Applications TDMA/CDMA/FM Cellular Rx LNA TDMA/CDMA PCS Rx LNA Low Noise Transmit Driver Amplifier ISM Band LNA/Driver General Purpose Amplification Commercial and Consumer Systems Functional Block Diagram Product Description The RF2442 is a low noise amplifier with a very high dynamic range designed for the receive front end of digital cellular applications at 900MHz, 1900MHz, and 2400MHz. It is designed to amplify low level signals with minimum noise contribution while operating in the harsh, interference-rich environments of newly deployed digital subscriber units. The device also functions as an outstanding PA driver amplifier in the transmit chain of digital subscriber units where low transmit noise power is a concern. The device supports trade-offs between linearity and current drain. The designer has control of these trade-offs with the choice of an external bias resistor. The IC is featured in a standard miniature 8-lead plastic MSOP package.

External RF and IF 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. This pin connects to pin 8 through a 150 resistor. This allows for simple biasing of the collector at pin 6. Refer to Application Schematics 1 and 3. Ground connection. For best performance, keep traces physically short and connect immediately to ground plane. RF input pin. This pin is internally DC-blocked and matched to 50 for frequencies above 1GHz. When using below 1GHz, it is recommended that this pin be matched with series inductance to series-resonate out the internal blocking capacitor. Refer to Application Schematics 1 and 2. Ground connection. For best performance, keep traces physically short and connect immediately to ground plane. No connection. This pin is typically left unconnected or grounded. LNA Output pin. This pin is an open-collector output. It must be biased to either VCC or pin 8 through a choke or matching inductor. This pin is typically matched to 50 with a shunt bias/matching inductor and series blocking/matching capacitor. Refer to application schematics. No connection. This pin is typically left unconnected or grounded. Optional power supply connection for biasing pin 6. This pin connects to pin 1 through a 150 resistor. This allows for simple biasing of the collector at pin 6. When used, this pin should be RF bypassed. Refer to Application Schematics 1 and 3. See pin 3.
