Cellular CDMA LNA
The RF2369 is a 3.0V switchable low noise amplifier with a bypass switch and very high dynamic range designed for digital cellular applications. This device functions as a front end LNA with an adjustable bias current that can be set externally. This feature allows the designer flexibility to trade-off RF performance versus current consumption. The RF2369 features a typical low bypass loss of 2 dB. This bypass performance allows a front end design, which meets all IS-98 requirements including Intermodulation Distortion (IMD) testing, using only two gain states and a single logic control line. In high-gain mode, the device exhibits 15.5 dB LNA gain, 11.5 dBm LNA IIP3, and 1.6 dB LNA noise figure.
The RF2369 is manufactured using a GaAs HBT process technology and is offered in a small industry-standard SOT23-6 package.
