Biasing and Operation
The AMMP-6231 is normally biased with a positive drain
supply connected to the VDD pin through a 0.1uF bypass
capacitor as shown in Figure 13. The recommended drain
supply voltage is 3V. It is important to have 0.1uF bypass
capacitor, and the capacitor should be placed as close to
the component as possible. Input and output ports are
DC-blocked. Impedance matching at input and output
ports are achieved on-chip, therefore, no extra external
component is needed. Aspects of the amplifier perfor-
mance may be improved over a narrower bandwidth by
application of additional conjugate, linearity, or low noise
(Gopt) matching No ground wires are needed because
all ground connections are made with plated through-
holes to the backside of the package. This part is only
conditionally stable. There is a potential region of insta-
bility around 42GHz and particular care is needed with
the source and load impedances presented to the part
around this frequency to avoid oscillations, especially at
low operating temperatures.
