3.3V satellite tuner for DVB-S eliminates external LNA

Sunnyvale, Calif.—Maxim Integrated Products has introduced the MAX2120 low-cost, zero-IF, direct-conversion tuner for satellite TV.

The MAX2120 receives QPSK signals in the 925-MHz to 2150-MHz range and down-converts them to baseband for demodulation. Its low 8.0dB noise figure eliminates the need for an external LNA, while its VCO autotuner function ensures ease of use. The MAX2120 is ideal for DVB-S and free-to-air applications in which low cost and ease of use are key requirements.

The MAX2120 operates from a single 3.3-V supply and consumes only 330-mW. It is designed to function using a low-cost 4MHz crystal, but an internal reference divider allows the user to select any crystal in the 4MHz to 8MHz range.

Fully specified over the 0°C to +70°C commercial temperature range, the MAX2120 is available in a 5mm x 5mm, 28-pin TQFN package.

Pricing: Starts at $3.50 (1000-up, FOB USA).
Availability: Now.
