Specifications of MAX2634EVKIT+

Lead Free Status / RoHS Status
Lead free / RoHS Compliant
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 con-
suming 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 compo-
nent 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 automo-
tive applications that require visual inspection of PCB
solder connections.
