EQUIVALENT CIRCUIT
C3, C4: 4700pF, 22uF in parallel
1 RF Input added Gate Voltage 1(Pin & VGG1)
2 Gate Voltage 2(VGG2)
3 Drain Voltage (VDD)
4 RF Output (Pout)
5 RF Ground (Case)
C1: 4700pF, C2: 1000pF, R1: suitable. Please refer the detail below.
VGG1=3.4V

External resistance connected to VGG1; impedance between Pin&VGG1 and ground needs to make high impedance
NOTE: Resistance between Gate Voltage 1, where RF is input, and ground equals to 15k ohm.
that doesn't prevent RF characteristic on this module.
