315MHz/433MHz Low-Noise
Amplifier for Automotive RKE
AC ELECTRICAL CHARACTERISTICS
(MAX2634 EV Kit, VCC = +2.2V to +5.5V, TA = -40°C to +125°C. Typical values are at VCC = +3.0V and TA = +25°C, unless otherwise
noted. PRFIN = -40dBm, SHDN = high.) (Note 2)

Note 2: Guaranteed by production test at TA = +25°C. Guaranteed by design and characterization at TA = -40°C and TA = +125°C.
Note 3: Measured with two tones located at 315MHz and 316MHz or 433MHz and 434MHz at -40dBm/tone.
Note 4: Guaranteed by design and characterization.
