Input and output tuned Gamma location for 1900MHz (1) and 2500MHz (2) For best performance, MGA-31489 is an input and output prematched driver amplifier. To bias MGA-31489, a +5V supply (Vdd) is connected to the output pin through a RF choke, L1 (which isolates the inband signal from the DC supply). The bypass capacitor helps to eliminate out of low band frequency signals from the power supply, C2 and C3. Blocking capacitors are required for its input (C7) and output (C8), to isolate the supply voltage from preceeding and succeeding circuits. C7 and L3 also play a part in input tuning to improve input return loss while L1 and C8 help in tuning output. The recommended output tuning is for achieving best OIP3, while meeting typical specifications for other parameters. 8 MGA-31489 Typical Scatter Parameters (1) Tc = 25° C, Vd = 5.0 V, Id = 69 mA, Zo = 50 Ω Freq GHz S11 Mag.
