MT2266 SINGLE-CHIP
DUAL-BAND LOW-POWER
DVB-T / DVB-H TUNER
PRODUCT BRIEF
The MT2266 is a direct conversion low-
power single-chip broadband tuner for VHF
Band III and UHF applications.
MT2266 Single Chip Dual-Band Tuner
The MicroTuner™ MT2266 is a
direct conversion, low-power, single-
chip broadband tuner optimized for
UHF and VHF Band III DVB-T and
DVB-H applications. It includes all
active circuitry required to implement
the complete RF-to-Baseband tuner
function.
The MT2266 has been
developed to give manufacturers
design flexibility and low operating
power, at low cost, without
compromising high performance.
The MT2266 is capable of
receiving UHF band and VHF Band
III frequencies, enabling
manufacturers to target low-power
portable and low-power PCTV
devices.
The combination of power
management, choice of architecture,
and Microtune’s patents-pending
ClearTune filtering technology
enables the MT2266 to operate at
325 mW.
High-volume consumer markets
demand low-cost products. The
MT2266 was designed for low cost.
The single-ended direct conversion
architecture eliminates the need for
baluns at the RF inputs and costly IF
SAW filters. To further reduce cost
and power, the UHF and VHF Band
III variable gain low noise amplifiers
(VLNA) and the voltage controlled
oscillators (VCO) are fully integrated.
The transmission environment
for mobile TV is extremely hostile.
Microtune's unique patents-pending
ClearTune filtering technology and
the excellent performance of
MT2266 will help to ensure that end
users will have a superior mobile TV
experience without picture
interruption in the middle of tall
buildings or hostile radio
environments.
