Cellular CDMA LNA

Thu, 06/28/2001 - 7:33am
RF Micro Devices announced the availability of the RF2369 low noise amplifier (LNA) and power amplifier (PA) driver amplifier for the cellular Code Division Multiple Access (CDMA) handset market.

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.
