Biasing and Operation
The recommended DC bias condition for optimum
performance, and reliability is Vg=+0.4 volts. There is
approximately zero current consumption for the gate
Vg
biasing because the FET mixer was designed as the pas-
RF
sive operation.

Figure 1 is a simple block diagram, as reference for
Figure 2. Figure 2 is a schematic of the image-rejection
(SSB) mixer MMIC connected to an off-chip quadrature
hybrid.
Figures 3 through Figure 11 show typical measure-
ment results under the image rejection operation. Data
presented for the AMMC-6550 was obtained using the
circuit described here. Please note that the image rejec-

tion and isolation performance is dependent on the
LO
selection of the low frequency quadrature hybrid. The
performance specification of the low frequency quadra-
ture hybrid as well as the phase balance and VSWR of the
interface to the AMMC-6550 will affect the overall mixer

performance.
No ground wired are needed since ground connections
are made with plated through-holes to the backside of
the device.
