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
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.
developed to give manufacturers
design flexibility and low operating
power, at low cost, without
compromising high performance.
receiving UHF band and VHF Band
III frequencies, enabling
manufacturers to target low-power
portable and low-power PCTV
devices.

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.
