MAX2634 Datasheet 315mhz/433mhz Low-noise Amplifier

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: 19-4383; Rev 1; 3/09 KIT ATION EVALU E L B AVAILA 315MHz/433MHz Low-Noise Amplifier for Automotive.

General Description

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.
