Greensboro, NC - RF Micro Devices, Inc. (RFMD) recently released the company's first gallium nitride (GaN) based CATV amplifier modules. The D10040200PH1 and D10040230PH1 are designed for use as power doubler amplifiers in current and next generation CATV infrastructure applications, including line amplification and hybrid fiber coaxial (HFC) optical nodes.
The D10040200PH1 and D10040230PH1 feature 20 dB and 23 dB of gain, respectively, and are the first power doubler amplifier modules to utilize an ultra-linear, high-efficiency GaN process technology. By combining multiple compound semiconductor technologies in a highly integrated, hybrid amplifier module RFMD designers are able to produce unmatched performance across all critical multi-carrier distortion parameters while also increasing output power capability and efficiency. With this unique blend of performance attributes, the D10040200PH1 and D10040230PH1 deliver significant improvements over competing devices in all key parameters and provide the utmost in design flexibility all while maintaining the ease of use CATV infrastructure original equipment manufacturers (OEMs) have come to expect from industry-standard SOT115J packaged amplifier modules.
As an example, CATV infrastructure designers can utilize either the D10040200PH1 or D10040230PH1 in HFC optical nodes to increase final power output by 2 to 3 dBmV over competing devices while maintaining equivalent multi-carrier distortion performance, in particular Carrier to Intermodulation Noise (CIN) levels. Alternatively, when best-in-class CIN performance is desired, RF output drive level may be reduced with minimal external tuning -- easing implementation for equipment OEMs.
RFMD's innovative implementation of GaN in this new generation of CATV amplifier modules dramatically improves CIN performance at an opportune time in the CATV market, said Alastair Upton, general manager of RFMD's Broadband and Consumer Business Unit. As multiple system operators (MSOs) increase digitally modulated transmissions over their CATV infrastructure and continue to implement fiber deep programs, the low distortion and high output power of these breakthrough products enable OEMs to better service the demand for higher-performance CATV infrastructure equipment.
Technical features of the D10040200PH1 and D10040230PH1 include:
Production quantities of D10040200PH1 and D10040230PH1 are available immediately and based on design win activity RFMD anticipates shipments will commence within the current calendar year.
