BG18B Datasheet | BeRex

Features - OIP3 = 31.5 d Bm @ 1900 MHz - Gain = 18.5 d B @ 1900 MHz - Output P1 d B = 18.9 d Bm @ 1900 MHz - Patented temperature pensation - Patented Over Voltage Protection Circuit - Ro HS2-pliant SOT-89 SMT package Product Description Be Rex’s BG18B is a high performance In Ga P/ Ga As HBT MMIC amplifier is internally matched to 50 Ohms and uses a patented temperature pensation circuit to provide stable current over the operating temperature range without the need for external ponents and a patented over voltage protection circuit to protect a internal device. The BG18B is designed for high linearity gain block applications that require excellent gain flatness. It is packaged in a Ro HS2-pliant with SOT-89 surface mount package.
