1) _{The gate voltage of the 1}st _{RF Amp is not blocked internally (see also Figure 1). Therefore VG1 must be blocked}
externally at RF IN.
2) _{The positive DC voltages of VD1, VD2 and VD3 are typically equal. The voltage range is typically between + 5.0 V}
and + 7.0 V.
3) _{The negative DC voltages of VG1, VG2 and VG3 are typically equal. The voltage range depends on the wanted}
drain current. A gate voltage of – 2.1 V will set I_D typically to 1.2 A at V_D = 7.0 V. In that case I_D1 will have about
70 mA, I_D2 about 270 mA and I_D3 about 900 mA.
