BLF1820-70
LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 60134).
THERMAL CHARACTERISTICS
Note
1. Determined under specified RF operating conditions.
CHARACTERISTICS
Tj =25 °C unless otherwise specied.
APPLICATION INFORMATION
RF performance in a common source class-AB circuit. Th =25 °C; Rth j-h = 1.15 K/W, unless otherwise specied.
Ruggedness in class-AB operation
The BLF1820-70 is capable of withstanding a load mismatch corresponding to VSWR = 10 : 1 through all phases under
the following conditions: VDS = 26 V; IDQ = 500 mA; PL = 65 W; f = 2000 MHz.
