General Description
The MAX2102/MAX2105† are low-cost direct-conversion tuner ICs designed for use in digital direct-broadcast satellite (DBS) television set-top box units. The direct-conversion architecture reduces system cost compared to devices with IF-based architectures.

Features
♦ Low-Cost Bipolar Design, Lowest Cost Architecture
♦ Operate from a Single +5V Supply
♦ 950MHz to 2150MHz Input Frequency Range*
♦ On-Chip Quadrature Generator, Dual-Modulus Prescaler (/64, /65)
♦ Input Levels
    -69dBm to -19dBm per Carrier (MAX2102)
    -60dBm to -19dBm per Carrier (MAX2105)
♦ Over 50dB AGC Control Range (MAX2102)
♦ Noise Figure = 13.2dB (MAX2102); IP3 = 6.5dBm (at 1450MHz)
♦ Automatic Baseband Offset Correction
♦ Easy Interface to MAX1002/MAX1003 Dual ADC and Popular Baseband ICs
