BeRex BG14B
BG14B is a high performance InGaP/ GaAs HBT MMIC amplifier, internally matched to 50 Ohms and uses a patented temperature compensation circuit to provide stable current over the operating temperature range without the need for external components. The BG14B is designed for high linearity gain block applications that require excellent gain flatness. It is packaged in a RoHS2-compliant with SOT-89 surface mount package.| Part No. | BG14B |

APPLICATIONS
Circuit L1 Vcc C3 C4 C5 RF In C1 BG14B C2 RF Out *C1, C2, C3 =100 pF ± 5%; C4 = 1000 pF ± 5%; C5 = 10uF; L1 = 39nH ±5% *40nH or higher value L1 improves RF performance at under 500MHz. *Optimum value of L1 may vary with board design. *C1,C2=8200pF, L1=1200nH for 70MHz application, Vcc=5.2V if 1200nH is used to compensate IR drop across L1. *L1:6.8nH, C1&C2:10pF for 3.5GHz Application.
