MAX2106 General Description

The MAX2106 low-cost, direct-conversion tuner IC is designed for use in digital direct-broadcast satellite (DBS) television set-top box units and is a pin-for-pin upgrade for the MAX2104. Its direct-conversion architecture reduces system cost compared to devices with IF-based architectures. The MAX2106 directly tunes Lband signals to baseband using a broadband I/Q downconverter. The operating frequency range spans 925MHz to 2175MHz.

The IC includes a low-noise amplifier (LNA) with gain control, I and Q downconverting mixers, lowpass filters with gain and frequency control, a local oscillator (LO) buffer with a 90° quadrature network, and a chargepump- based phase-locked loop (PLL) for frequency control. The MAX2106 has an on-chip LO, requiring only an external varactor-tuned LC tank for operation. The LO's output drives the internal quadrature generator and has a buffer amplifier to drive off-chip circuitry. The MAX2106 comes in a 48-pin thin quad flat-pack package with exposed paddle (EP).
