Mitsumi Electronics Corp. has developed an integrated tuner/demodulator subsystem using Microtune Inc.'s MT2111 silicon tuner as the core RF component. Mitsumi's module, the DCT33-J02D, is an integrated QAM tuner demodulator. It is a pre-tested, manufacturing-ready solution that allows cable set-top boxes to receive, tune and demodulate digital cable signals, and targeted initially for the Japanese market.

Microtune says its MT2111 tuner bring unparalleled integration of RF technology by combining the tuner, low noise amplifier, intermediate frequency amplifier, mixers, oscillators, and input controls on the same chip. Packaged in a miniature 1/4-inch square chip, this integrated design approach offers a low RF implementation cost combined with superior linearity, image rejection and frequency response.

When integrated into modules for set top boxes, Microtune claims the MT2111 is engineered to offer superior reception for cable broadcast applications including high definition (HD), consistent with extended cable services, such as personal video recorders, consumer IP-based video phones and video conferencing systems.

Mitsumi Electronics is a subsidiary of Mitsumi Electric Co. Ltd. Its electronic components include ICs, connectors, RF tuners and modules that are sold through OEM and distribution channels.
