RF2373 3.3V LOW NOISE AMPLIFIER/ 3V DRIVER AMPLIFIER Package Style: SOT 5-Lead Features Low Noise and High Intercept Point Adjustable Bias Current Power Down Control Single 2.7V to 5.0V Power Supply 0.4GHz to 4GHz Operation SOT 5-Lead Package RF IN 1 GND1 2 Applications 5 GND2 BIAS 3 WiFi LNA/Driver GPS LNA CDMA PCS LNA Low Noise Transmit Power Amplifier General Purpose Amplification Driver Amplifier for TX Power Amplifier 4 RF OUT Functional Block Diagram Product Description The RF2373 is a low noise amplifier with a high dynamic range designed for WiFi, WiMAX, and digital cellular applications. The device functions as an outstanding front end low noise amplifier or driver amplifier in the transmit chain of digital subscriber units where low transmit noise power is a concern. When used as an LNA, the bias current can be set externally. When used as a PA driver, the IC can operate directly from a single cell Li-ion battery and includes a power down feature that can be used to completely turn off the device. The IC is featured in a standard SOT 5lead plastic package.

Extended application of Absolute Maximum Rating conditions to the device may reduce device reliability. Specified typical performance or functional operation of the device under Absolute Maximum Rating conditions is not implied. RoHS status based on EUDirective2002/95/EC (at time of this document revision). The information in this publication is believed to be accurate and reliable.

RFMD reserves the right to change component circuitry, recommended application circuitry and specifications at any time without prior notice. NOTE: Exceeding any one or a combination of the above maximum rating limits may cause permanent damage. Input RF transients to +15dBm will not harm the device. For sustained operation at inputs >+5dBm, a small dropping resistor is recommended in series with the VCC in order to limit the current due to self-biasing to <32mA. Furthermore, while the LNA is in Bypass Mode, and for sustained operation at the input, +10dBm is the maximum recommended power level for Frequencies above 2300MHz. +5dBm is the maximum recommended power level for Frequencies <2300MHz.
