RF2302PCBA-H

RF2302 4 Typical Applications • CDMA Cellular/PCS and JCDMA Systems • TDMA Cellular/PCS Systems • GSM Systems • Wireless Local Loop Systems • Wideband CDMA Systems • PDC Systems (950MHz and 1450MHz) BROADBAND LINEAR VARIABLE GAIN AMPLIFIER Product Description The RF2302 is a broadband linear variable gain amplifier that was designed specifically for digital communications systems that require linear amplification over a wide gain control range. It is suitable for use in CDMA or TDMA systems in the cellular or PCS band, in DAMPS systems, and in PDC systems. Operating supply voltage ranges from 3V to 6V. The device operates over a large frequency band, from 100MHz to 2000MHz, and is tuned to a specific frequency band with an output bias feed inductor and blocking capacitor. Bias optimization may be achieved by adjusting the voltage to pin 8 (PD). The IC is manufactured on an advanced Gallium Arsenide Heterojunction Bipolar Transistor (GaAs HBT) process and is featured in a new standard miniature 8-lead plastic MSOP package.
