MAX2634AXT+T by Analog Devices

315MHz/433MHz Low-Noise Amplifier for Automotive RKE


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 supply. An integrated logic-controlled low-power shutdown mode reduces power consumption to 0.1µA and replaces the two transistors typically required to implement the shutdown function in discrete-based RKE LNA solutions. The device further reduces component count by integrating the output matching and DC-blocking components, and only requires a single inductor to match the input for best noise figure and input return loss. The device is available in a small 6-pin (2.0mm x 2.2mm x 0.9mm) lead-free SC70 package for automotive applications that require visual inspection of PCB solder connections.
