Preliminary specication
UHF push-pull power LDMOS transistor
BLF2022-120
THERMAL CHARACTERISTICS
Note
1. Thermal resistance is determined under nominal 2-tone RF operating conditions.
CHARACTERISTICS
Tj =25 °C unless otherwise specied.
Note
1. Capacitance of die only.
APPLICATION INFORMATION
RF performance in a common source class-AB circuit. Th =25 °C; Rth mb-h = 0.65 K/W, unless otherwise specied.
Ruggedness in class-AB operation
The BLF2022-120 is capable of withstanding a load mismatch corresponding to VSWR = 10 : 1 through all phases under
the following conditions: VDS = 28 V; f = 2170 MHz, PL = 120 W (CW).
