Fabricated using the company's advanced CMOS process, the LNA accepts separate AM and FM signal paths and delivers 30 dB of gain range to each. This fully integrated solution reduces BOM cost while ensuring optimized performance and carefree operation.

The MAX2180 is designed to operate from 148 kHz to 162.5 MHz and incorporates many features that advance current antenna architectures. This LNA also reduces solution size and complexity. The self-controlled AGC loop includes on-chip power detectors to ensure that the signal level within each channel is continually optimized to negate the effects of antenna mobility.

This design eliminates the need for external PIN diodes and associated driver circuits. A voltage regulator and pass transistor provide a stable supply over a wide 8 V to 24 V voltage range. A wide voltage range can be particularly useful in applications such as hybrid or electric vehicles where sudden swings in supply are common.

The MAX2180 also provides on-chip thermal protection that automatically limits junction temperatures during extreme thermal conditions. Available in a small (4 mm x 4 mm) TQFN package, the device is fully specified over the -40 °C to +85 °C extended temperature range.
