RF Micro Devices has introduced the ML5825 frequency transverter. The ML5825 is designed to upconvert transmitted 2.4 GHz signals to 5.8 GHz and downconvert received 5.8 GHz signals to 2.4 GHz and is specifically optimized for streaming video applications.
The addition of this frequency translation functionality to a pre-existing 2.4 GHz ISM band radio allows original equipment manufacturers (OEMs) to quickly bring to market products for operation in the 5.8 GHz ISM band, including digital cordless phones and custom wireless data systems such as streaming audio and video appliances.The ML5825 incorporates, on a single die, a voltage controlled oscillator (VCO), phase locked loop (PLL)-based synthesizer, low noise amplifier (LNA), receive and transmit bandpass filtering and mixers, and a transmit pre-driver. By offering a digitally controlled 18 dB gain step, the ML5825 allows radio designers to optimize third order input intercept point (IIP3) performance and noise figure based on specific application needs. Additionally, the ML5825 offers a low power standby mode of 10 microamps to minimize average power consumption, leading to longer battery life in portable applications. 'The movement of many data communications systems to the 5.8 GHz ISM band presents an opportunity to leverage the existing system design know-how accumulated from 2.4 GHz products,' said Alastair Upton, general manager of RFMD's Broadband and Consumer Business Unit. 'The ML5825 gives OEMs the ability to rapidly bring new 5.8 GHz products to market with low risk and a reduced total cost of implementation.' |
