Analog Devices Intros AD8340 and AD8341 RF ICs
Analog Devices Inc. (ADI, Wilmington, MA) announced its new AD8340 and AD8341 vector modulators, which are single-chip radio frequency integrated circuits (RFICs) that enable manufacturers of high-power amplifiers and radio transceivers for cellular base station equipment to adjust both amplitude and phase of their RF carriers.
The AD8340 operates over a frequency range from 700 MHz to 1.0 GHz, while the AD8341 operates from 1.5 GHz to 2.4 GHz. Both parts are pin- and functionally compatible, allowing one standardized footprint to be used for any cellular band of interest. The AD8340 and AD8341 complement ADI's AD8302 gain and phase detector, providing a complete measurement and control solution. The AD8340, AD8341 and AD8302 are suitable for use in feed-forward linearization control loops and RF pre-distortion applications within cellular MCPA equipment.
The AD8340 and AD8341 RF vector modulators are fabricated on ADI’s proprietary, high-performance, 25 GHz, silicon-on-insulator, complementary bipolar IC process. Available in 24-lead, chip-scale packaging, the parts are priced at $7.50 per unit in 1,000-piece quantities.
