RFHIC Introduces 3-Way & 4-Way Active Divider for Digital TV and Set-Top-Box Applications
Covering 45 ~ 1000 MHz, with 8 dB & 6 dB gain, good gain flatness & noise figure, great VSWR & Linearity
Korea (August 17, 2009) – RFHIC Corporation, manufacturer of active RF & MW components and hybrids for
wireless telecommunication markets, released 3-way & 4-way Active Divider for Digital TV and Set top box
is a low cost SMD type 3-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 which use multiple
tuners will need RF power splitters to divide the RF signal efficiently before the tuner. AD311 covers 45 ~ 1000
MHz, with 8 dB gain, and has good gain flatness & noise figure, great VSWR & Linearity.
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 MMIC(Monolithic microwave integrated circuit) 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, Mr. BG Han.

lead-free RoHS conforming device, using a low cost, SMD QFN 3x3 16 pin Plastic Package with a 5V single power
RFHIC also has AD412, which is a 4-way active divider. Both devices are matched for 75ohm
application, but 50ohm applications including IF frequency & 800MHz bands can also benefit full performance with
only a small matching change. All devices are 100% DC tested and RF tested.
Both AD311 and AD412 are
available in sample quantity immediately. Production volumes will be available for shipment from October of 2009.
