Frequency Transverter targets streaming video applications.
May 19, 2008 -
Designed to upconvert transmitted 2.4 GHz signals to 5.8 GHz and downconvert received 5.8 GHz signals to 2.4 GHz, Model ML5825 incorporates VCO, PLL-based synthesizer, low noise amplifier, receive/transmit bandpass filtering and mixers, and transmit pre-driver. Stand-by mode of 10 µA minimizes average power consumption, extending battery life in portable applications. Housed in 4 x 5 x 0.9 mm QFN package, device features 4 dB noise figure in high gain mode and -14 dBm IIP3 in low gain mode.
RFMD® Releases 2.4 GHz to 5.8 GHz Frequency Transverter
GREENSBORO, N.C., May 14 /- RF Micro Devices, (Nasdaq: RFMD), a global leader in the design and manufacture of high-performance semiconductor components, today 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."
Technical features of the ML5825 include:
-- Input voltage operation from 2.8 to 3.6 V
-- Selectable transmit output power
-- 4 dB noise figure in high gain mode
-- -14 dBm IIP3 in low gain mode
-- Integrated VCO/PLL spurious content -60 dBc or better
The ML5825 is packaged in a 4 x 5 x 0.9 mm, 28-pin QFN package and is priced at $1.46 each, in quantities of 10,000 units with samples available immediately.
