MAX2634 Datasheet (Maxim Integrated Products) - 315MHz/433MHz Low-Noise Amplifier

MAX2634, 315MHz/433MHz Low-Noise Amplifier

The MAX2634 low-noise amplifier (LNA) with low-power shutdown mode is optimized for 315MHz and 433.92MHz automotive remote keyless entry (RKE) applications.

At 315MHz, the LNA achieves 15.5dB power gain and a 1.25dB noise figure while only consuming 2.5mA of supply current from a 2.2V to 5.5V power
