RF Micro Devices Inc. debuts 1.2GHz broadband transmission products are designed for CATV operators and their subscribers. The 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 new products include the RFPD2580, RFPP2590 and RFOS601x. The RFPD2580 is a power doubler amplifier that uses RFMD's GaN technology to achieve 22.5dB gain at 1.2GHz and high signal output capability. The RFPP2590 is a hybrid push-pull amplifier module that delivers extremely low distortion and consumes just 240mA from a 24V supply. The RFPP2590 is a companion part to the RFPD2580, and the two products combine to optimise performance in CATV line extender amplifiers deployed in CATV distribution networks.

The RFOS601x is an optical receiver module designed for use in hybrid fibre coax optical nodes. Optical nodes reside at the edge of the fibre network, converting light into electrical signals for transmission to CATV STB and home routers. The low distortion of the RFOS601x enables "fibre-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 RFPD2580 features 45-1200MHz bandwidth, 22.5dB minimum gain at 1200MHz and 450mA power consumption maximum at 24Vdc. The offers 45-1200MHz bandwidth, 23dB minimum gain at 1200MHz and 240mA power consumption maximum at 24Vdc. It also features 0.8dB gain flatness and low distortion at CTB = -60dBc max, CSO = -65dBc max. The RFOS601x packs 45-1200MHz bandwidth, 6.3pA/sqr (Hz) maximum at 1200MHz EINC with 32dBA/W O/E at 1200MHz.

The RFPD2580, RFPP2590, and RFOS601x are all available in industry-standard SOT115J packages and are available for sampling immediately.
