BG18C Datasheet | BeRex

Features - OIP3 = 32.5 d Bm @ 1900 MHz - Gain = 20.9 d B @ 1900 MHz - Output P1 d B = 18.8 d Bm @ 1900 MHz - Patented temperature pensation - Patented Over Voltage Protection Circuit - Ro HS2-pliant SOT-89 SMT package Product Description Be Rex’s BG18C 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 BG18C 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. Applications - Base station Infrastructure/RFID - mercial/Industrial/Military wireless system Applications Circuit RF In C1 L1 BG18C Vcc C3 C4 C5 C2 RF Out - C1, C2, C3 =100 p F ± 5%; C4 = 1000 p F ± 5%; C5 = 10u F; L1 = 33n H ±5% - C1,C2 = 10n F; L1 = 2.7u H for IF Bandwidth - Optimum value of L1 may vary with board design.
