RF2373 3V LOW NOISE AMPLIFIER/ 3V DRIVER AMPLIFIER RoHS Compliant & Pb-Free Product Package Style: SOT 5-Lead Features Low Noise and High Intercept Point Adjustable Bias Current Power Down Control Single 1.8V to 6.0V Power Supply 400MHz to 3GHz Operation Extremely Small SOT 5-Lead Package RF IN 1 GND1 2 BIAS 3 Applications 5 GND2 WLAN 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 very high dynamic range designed for WLAN 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 5-lead plastic package.
