300MHz to 450MHz High-Efficiency,
Crystal-Based +13dBm ASK Transmitter
ABSOLUTE MAXIMUM RATINGS
VDD to GND ..........................................................-0.3V to +4.0V
All Other Pins to GND ................................-0.3V to (VDD + 0.3V)
Continuous Power Dissipation (TA = +70°C)
8-Pin SOT23 (derate 8.9mW/°C above +70°C)............714mW
Operating Temperature Range .........................-40°C to +125°C
Storage Temperature Range .............................-60°C to +150°C
Junction Temperature ......................................................+150°C
Lead Temperature (soldering, 10s) .................................+300°C
Stresses beyond those listed under âAbsolute Maximum Ratingsâ 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.
ELECTRICAL CHARACTERISTICS
(Typical Application Circuit, all RF inputs and outputs are referenced to 50â¦, VDD = +2.1V to +3.6V, TA = -40°C to +125°C, unless
otherwise noted. Typical values are at VDD = +2.7V, TA = +25°C, unless otherwise noted.) (Note 1)
