Product Description
The RF2157 is a high-power, high-efficiency linear amplifier IC targeting 3V handheld systems. The device is manufactured on an advanced Gallium Arsenide Heterojunction Bipolar Transistor (HBT) process, and has been designed for use as the final RF amplifier in dual-mode 3V CDMA and TDMA handheld digital equipment, spread-spectrum systems, and other applications in the 1710MHz to 1910MHz band. The device is packaged in a compact 4mmx4mm LCC, as well as a 4mmx4mm MLF (micro leaded package). The frequency response can be optimized for linear performance over 1710MHz to 1910MHz. The device features a digital mode switch which can be used to minimize operating current under low output power conditions.
