! APPLICATION CIRCUIT
・ L1 and L2 form the input matching circuit. The LNA has integrated coupling and DC-blocking capacitor at
・ L3 is a matching inductor of the integrated 1
・ L4 is an output matching inductor.
・ C1 is a coupling and DC-blocking capacitor at the output.
・ C2 and C3 are bypass capacitors. They should be connected between L3 and L4. C2 should be placed to
・ R1 is a stability resistor at high frequency, and it should be connected to the terminal1.
・ Ground terminal (No.2, 5, 6) should be connected to the ground plane as close as possible for good RF
・ For good performance, the terminal1,3 and 4 should not be coupled though floating-capacitance which
