5-6000 MHz Cascadable InGaP HBT Gain Block

BG14B

BeRex’s BG14B is a high performance InGaP/

GaAs HBT MMIC amplifier, internally

matched to 50 Ohms and uses a patented

temperature compensation circuit to pro-

vide stable current over the operating tem-

perature range without the need for exter-

nal components. The BG14B is designed for

high linearity gain block applications that

require excellent gain flatness. It is packaged

in a RoHS-compliant with SOT-89 surface

Operation of this device above any of these parameters may result in permanent damage.

*less than 20nH improves RF performance at over 1.9GHz.

*40nH or higher value L1 improves RF performance at under 500MHz.

*Optimum value of L1 may vary with board design.
