RFHIC Corp., a manufacturer of active RF and MW components and hybrids for wireless telecommunication markets, released a three-way and four-way active divider for Digital TV and set top box applications.

AD311 is a low cost SMD type three-way active divider for LCD TV, PDP TV, CATV Set top box, or GE-PON applications. Most of the TV system and set top box systems for CATV, Cable modem, Digital TV, Analog TV applications that use multiple tuners will need RF power splitters to divide the RF signal efficiently before the tuner. AD311 covers 45 to 1000 MHz, with 8 dB gain, and has good gain flatness and noise figure, great VSWR and linearity.

“Consumer electronics is a very competitive market, but with great potential. With technical leadership and proven products, we believe customers will benefit from the low cost and sturdy design of AD311. The device uses Gallium Arsenide Enhancement Mode PHEMT (E-PHEMT) technology, and is a Monolithic microwave integrated circuit (MMIC) designed for enhanced reliability and low power consumption, which will be very beneficial for system architecture. AD311 also has an internal bias circuit to maintain stable performance against temperature and power fluctuations, and have significant multi-channel distortion enhancement,” said the Chief Developer, BG Han.
