Product Description
Typical Performance¹
BeRex’s BGS1 is a high SiGe HBT MMIC am-
plifier, internally matched to 50 Ohms with-
out the need for external components. De-
signed to run directly from a 3.2V supply.
The BGS1 is designed for high linearity 3.2V
gain block applications . It is packaged in a
RoHS-compliant with SOT-363 surface
mount package.

*C1, C2, C3 =100 pF ± 5%; C4 = 1000 pF ± 5%; C5 = 10uF; **L1 = 56nH
**less than 56nH improves RF performance at over 0.9GHz.
*1uH or higher value L1 improves RF performance at under 900MHz.
*Optimum value of L1 may vary with board design.
