RFMD launches first 1.2GHz CATV amplifiers, enabling enhanced, bandwidth-driven services

RF Micro Devices Inc of Greensboro, NC, USA has launched what it claims is the industry's first 1.2GHz broadband transmission products (available for sampling now, in industry-standard SOT115J packages), enabling enhanced, bandwidth-driven services for CATV operators and their subscribers.

With bandwidth of 45–1200MHz, the new RFPD2580, RFPP2590, and RFOS601x products provide options for cable operators to upgrade their network infrastructure to 1.2GHz, enhancing their network performance and providing bandwidth for growing broadcast and narrowcast services such as HDTV and emerging 3D HDTV.

The RFPD2580 is a power doubler amplifier that uses RFMD’s gallium nitride (GaN) technology to achieve 22.5dB minimum gain at 1.2GHz and what is claimed to be best-in-class signal output capability. Power consumption is 450mA maximum at 24VDC.

The RFPP2590 is a hybrid push-pull amplifier module that delivers extremely low distortion (CTB = –60dBc max, CSO = –65dBc max) and consumes just 240mA from a 24V supply. With 23.0dB minimum gain at 1200MHz and 0.8dB gain flatness, the RFPP2590 is a companion part to the RFPD2580, and the two products combine to optimize performance in CATV line extender amplifiers deployed in CATV distribution networks.

The RFOS601x is an optical receiver module designed for use in hybrid fiber coax (HFC) optical nodes (at the edge of the fiber network, converting light into electrical signals for transmission to CATV set-top boxes and home routers). RFMD says that the RFOS601x’s low distortion enables ‘fiber-deep’ networks, in which the optical network is extended closer to the CATV subscriber, supporting higher data rates and addressing the increasing demand for high-bandwidth video and broadband services. The RFOS601x is available with FC/APC (RFOS6012) or SC/APC (RFOS6013) optical connectors.

RFMD claims to be the first firm to introduce GaN technology in CATV hybrids, allowing CATV operators to achieve 3dB higher output power without an increase in current consumption, or a 20% reduction in current consumption without a decrease in output power. The firm adds that its GaN technology also helps carriers expand the utilization of their cable networks to better compete with satellite and fiber-to-the-home (FTTH) networks.
