Lead Temperature (soldering, 10s) .................................+300°C
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
DC ELECTRICAL CHARACTERISTICS
(V CC = +2.7V to +5.5V, V TUNE = +0.4V to +2.4V, V SHDN ≤ +2V, OUT = connected to 50 Ω load, T A = -40°C to +125°C. Typical values
are at V CC = +3.0V, T A = +25°C, unless otherwise noted.) (Note 1)

Note 1: Minimum and maximum limits are guaranteed by production test at T A = +25 ° C and T A = +125 ° C. Minimum and maximum
limits are guaranteed by design and characterization at T A = -40 ° C.
Note 2: Tuning gain is measured at the oscillator’s guaranteed frequency limits.
Note 3: Turn-on time to within 3dB of final output power
Note 4: Turn-off time to output power of -10dBm.
