(Note: To assure stable operation bias supply feeds should be bypassed to ground with a capacitor, Cb ≥ 100 pF typical.)
Biasing for Fundamental Mixing
The recommended DC bias condition for the AMMC-
3040 LO amplifier when used as a fundamental frequen-
cy mixer is with all four drains connected to a single 3.5
to 4.5 V supply and all four gates connected to an adjust-
able negative supply voltage as shown in Figure 16(a).
The gate voltage is adjusted for a total drain supply cur-
rent of typically 150 to 250 mA.
The second, third, and fourth stage DC drain bias lines
are connected internally and therefore require only a
single bond wire. A separate bond wire is needed for the
first stage DC drain bias, V

The third and fourth stage DC gate bias lines are con-
nected internally. A total of three DC gate bond wires are
required: one for V
connection. The internal matching circuitry at the RF in-
put creates a 50-ohm DC and RF path to ground. Any
DC voltage applied to the RF input must be maintained
below 1 volt, otherwise, a blocking capacitor should be
used. The RF output is AC coupled.
No ground bond wires are needed since the ground con-
nection is made by means of plated through via holes to
the backside of the chip.
