ML5825

ML5825 www.DataSheet4U.com 2.4GHz to 5.8GHz Frequency Translator ADVANCED Datasheet GENERAL DESCRIPTION The ML5825 is a high integration 2.4GHz - 5.8GHz frequency translator (transverter). It upconverts 2.4GHz signals to 5.8GHz and downconverts received 5.8GHz signals to 2.4GHz. Transmit and receive utilize the same low noise fixed local oscillator (LO). It is intended to be used in conjunction with a 2.4GHz transceiverbased solution to quickly and easily develop a 5.8GHz solution while fully leveraging previous development. The ML5825 receive chain contains a Low Noise Amplifier (LNA), bandpass filter and image reject down conversion mixer. A digitally controlled 18dB gain step in the receive chain provides an innovative solution for optimizing IIP3 (low gain mode) and Noise Figure (high gain mode). On the transmit side, the ML5825 buffers and upconverts a differential 2.4GHz signal to 5.8GHz, where it is filtered and amplified. The ML5825’s PLL accepts two industry-standard input clock frequencies. The ML5825’s low STANDBY MODE current maximizes battery life. Power supply regulation is included in the ML5825, providing circuit isolation and consistent performance over supply voltages between 2.8V-3.6V.
