RF Micro Devices Inc. (RFMD) announced the addition of two new products to the company's extensive portfolio of broadband transmission products. The two newly released products are RFMD's D10040300GTH hybrid power doubler amplifier module and OS10040320PW optical receiver module. Both are designed for current- and next-generation CATV infrastructure applications.

The D10040300GTH hybrid power doubler amplifier module is specifically designed for CATV infrastructure applications including line amplification and hybrid fiber coaxial (HFC) optical nodes. The D10040300GTH operates from 40 MHz to 1 GHz while typically maintaining 30 dB or better of gain across the entire frequency range -- an industry first among available power doublers. The D10040300GTH helps cable operators to upgrade existing distribution networks to 1 GHz and enables bandwidth-intensive services such as high-speed data, voice and HDTV. Operators can also exploit the linearity of the device to reduce the number of amplifiers in the network.

The OS10040320PW is a 1 GHz hybrid high dynamic range optical receiver module designed for use in HFC optical nodes and deep fiber network installations. The OS10040320PW contains a single-mode optical input suitable for wavelengths from 1290 to 1600 nm, a terminal for monitoring the PIN diode current and an electrical output with an impedance of 75 Ohms. The equivalent input noise current (EINC) performance of the OS10040320PW is among the industry's lowest at 5 pico Amps per root Hertz, typical performance, helping cable operators to implement "fiber deep" solutions as they upgrade to 1 GHz networks. Specifically, by enabling the optical node portion of HFC networks to be placed deeper into CATV networks, the OS10040320PW minimizes requirements for more costly Erbium-doped fiber amplifiers (EDFA).

Alastair Upton, General Manager of RFMD's Broadband Components business unit, said, "RFMD is pleased to support multiple system operators (MSO) and their infrastructure equipment providers with innovative new products such as the D10040300GTH and OS10040320PW. As MSOs continue to upgrade their CATV infrastructure to 1 GHz and implement fiber deep programs, these new products help to lower overall upgrade costs and enhance system performance."
