MAX2634AXT+T

The MAX2634AXT+T is a 315MHz/433MHz ultra low current low noise amplifier (LNA) for RKE solutions with low noise figure and shutdown mode in 6 pin SC-70 package. It is optimized for 315MHz and 433.92MHz automotive remote keyless entry (RKE) applications. At 315MHz, the LNA achieves 15.5dB power gain and 1.25dB noise figure at TA = +25°C while only consuming 2.5mA of supply current from 2.2V to 5.5V power supply. An integrated logic controlled low power shutdown mode reduces power consumption to 0.1μA and replaces two transistors typically required to implement the shutdown function in discrete based RKE LNA solutions. The device further reduces component count by integrating output matching and DC blocking components. It requires a single inductor to match input for best noise figure and input return loss. The MAX2634 is used in tire pressure monitoring systems (TPMS), garage door openers and telemetry receivers.
