AMMP-6522 Application and Usage
Biasing and Operation
The AMMP-6522 is normally biased with a positive
drain supply connected to the VDD pin and a negative
gate voltage connected to the Vg pin through bypass
capacitors as shown in Figure 17. The recommended
drain supply voltage is 4 V and gate bias voltage is -1 V.
The corresponding currents are 75 mA and 0.1 mA re-
spectively. The typical required LO level is +15 dBm and
it should come from a low noise driver to ensure that
overall Front End NF is low.
The image rejection performance is dependent on the
selection of the IF quadrature hybrid. The performance
of the IF hybrid as well as the phase balance and VSWR
of the interface to the AMMP-6522 will affect the overall
front end performance.
There is minimal performance degradation if Vdd is
lowered to 3 V or raised to 5 V. If lower current is required,
then Vdd = 3 V will provide considerably similar RF
performance.

The recommended Vg is -1 V. However, depending on
the operating frequency, Vg can be changed to achieve
better performance for that particular frequency.
Please refer to Figures 9 and 10 for how to best select the
appropriate Vg for the intended frequency of operation.
Theoretically IF frequencies can be as low as DC. How-
ever, when direct conversion is used (IF = DC), a so-called
phenomenon DC-offset could occur at the two IF out-
puts. In most practical applications, IF should be more
than a few hundreds kHz to avoid DC-offset correction.
Refer the Absolute Maximum Ratings table for allowed
DC and thermal condition.
