MAX2634

315MHz/433MHz Low-Noise

Ampliﬁer for Automotive RKE

General Description

Features

● Optimized for 308MHz, 315MHz, 418MHz,

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 shut-

down 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.
