EXPLANATION
RF port. This port is connected with P2 port by controlling
2pin-VCTL(H) (+2.5~+6.5V) and 4pin-VCTL(L) (-0.2~+0.2V).
This port is connected with P4 port by controlling 2pin-VCTL(L)
(-0.2~+0.2V) and 4pin-VCTL(H) (+2.5~+6.5V).
A DC cut capacitor 56pF is reguired at this terminal to block DC
voltage of inner circuit.
Control port1. Please connect bypass capacitor (10pF) between this
terminal and GND close to this IC.
Ground terminal. Please connect this terminal with ground plane as
close as possible for excellent RF performance.
Control port2. Please connect bypass capacitor (10pF) between this
terminal and GND close to this IC.
RF port. This port is connected with P1 port by controlling
2pin-VCTL(L) (-0.2~+0.2V) and 4pin-VCTL(H) (+2.5~+6.5V).
