SGA-5486 DC-2400 MHz 3.5V SiGe Amplifier
Pin #
1
Function
Description
RF IN
RF input pin. This pin requires the use of
an external DC blocking capacitor
chosen for the frequency of operation.
GND
Connection to ground. Use via holes for
best performance to reduce lead
inductance as close to ground leads as
possible.
RF OUT/ RF output and bias pin. DC voltage is
BIAS
present on this pin, therefore a DC
blocking capacitor is necessary for
proper operation.
GND
Sames as Pin 2
