ML5825
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 transceiver-
based 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.
