Note: * as blocking capacitor, not required in actual application circuit.
For best performance, MGA-31589 requires only simple input and output matching network. The C3, C4, and L3 act
as the output tuning circuitry for matching and OIP3 optimization. Bandpass network C1,C2, and L1 forms the input
matching network. To bias MGA-31589, a +5 V supply (Vdd) is connected to the output pin thru a RF choke, L2 (which
isolates the inband signal from the DC supply). The low frequency bypass capacitors C6 and C7 help to eliminate low
frequency signals from power supply. Blocking capacitors are required for its input (C8) and output (C9), to isolate the
supply voltage from succeeding circuits. The recommended output tuning is for achieving wideband best OIP3, while
meeting typical specications for other parameters.
