UHF power LDMOS transistor

BLF647

APPLICATION INFORMATION

RF performance in a common source class-AB circuit. Th =25 °C; Rth mb-h = 0.2 K/W, unless otherwise speciﬁed.

Ruggedness in class-AB operation

The BLF647 is capable of withstanding a load mismatch corresponding to VSWR = 10 : 1 through all phases under the

following conditions: VDS = 28 V; f = 100 MHz at rated load power.

The BLF647 is capable of withstanding abrupt source or load mismatch errors under the nominal power conditions.

Impedances (per section)

At f = 600 MHz, PL = 120 W, VDS = 28 V and IDQ = 1 A: Zin = 1.0 + j2.0 Ω and ZL = 2.7 + j0.7 Ω.

At f = 800 MHz, PL = 150 W, VDS = 32 V and IDQ = 1 A: Zin = 1.0 + j3.8 Ω and ZL = 1.8 + j0.7 Ω.
