Networks are one of the key infrastructures for the broadcasting and
telecommunication industry. FTTH, fiber to the home, is the basis for the
optical cable installation as well. RF MMIC devices are used in many of the
applications for converting optical signals to RF signals and vice versa. CATV
broadcasting, satellite broadcasting, high speed internet, IPTV(Internet
Protocol Television), VOD(Video on Demand) and other telecommunication
applications can be converged through optical networks and is now expanding its
market in various territories.
RFHIC recently developed E-pHEMT (Enhancement Mode Pseudomorphic High Electron Mobility Transistor) MMIC for this growing market of optical network transceiver and receiver markets. Typical applications these MMIC products are used are; FTTH, G-PON, Optical nodes, CPE, RFoG (RF over glass), MDU-PON and etc.
For the forward path, 48~1002MHz, 50~2200MHz, 70~2600MHz application for single and push-pull packages are available. AE314, AQ102, AP112, AE342, AE460, and AE427 devices are available in SOT-89 low cost packages. AP230, AE514, AE617, and AE618 devices are available in SOIC-8 packages as well.
For reverse path applications, one or two matching circuit changes will enable AE314, ACQ102, AP112, AE342, AE460, AE427, AP230, AE514, and AE617 devices to perform perfectly on 5~65MHz and 5~200MHz frequency bands. Additional information for forward and reverse amplifier can be found from the MMIC web page.
For G-PON (Gigabit Passive Optical Network), or other applications splitting signals, active dividers like AD211 and AD311 can also be used. You can find the summary of active dividers from the divider product page.
RFHIC focused engineering efforts to increase gain of the MMIC to 20dB or higher, while lowering noise figures. RFHIC devices also have protective diodes built-in to the MMIC to improve against EDS, Surge, and high-input power. These protections will be critical for enhancing reliability of your systems in the field.
