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
biasing because the FET mixer was designed as the pas-
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 o -chip quadrature
hybrid.
Figures 3 through Figure 11 show typical down conver-
sion measurement results under the image rejection
operation. Data presented for the AMMC-6550 was
obtained using the circuit described here. Please note
that the image rejection and isolation performance
is dependent on the selection of the low frequency
quadrature hybrid. The performance speci cation of the
low frequency quadrature hybrid as well as the phase
balance and VSWR of the interface to the AMMC-6550
will a ect the overall mixer performance.
No ground wires are needed since ground connections
are made with plated through-holes to the backside of
the device.
The AMMC-6550 is not recommended for up conversion
applications.
