NGA-186 DC-6.0 GHz 4.1V GaAs HBT
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. For best
performance use via holes (as close to
ground leads as possible) to reduce lead
inductance.
RF OUT/
BIAS
RF output and bias pin. DC voltage is
present on this pin, therefore a DC
blocking capacitor is necessary for
proper operation.
GND Same as Pin 2.
