Notes:
1. S-parameters are measured with R&D Eval Board as shown in Figure 19. Board and connector eects are included in the data.
2. Noise Figure is measured with R&D Eval Board as shown in Figure 19, and with a 3-dB pad at input. Board and connector losses are already de-
embeded from the data.

Biasing and Operation
The AMMP-6522 is normally biased with a positive
drain supply connected to the Vd 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 re-
quired, then Vd = 3 V will provide considerably similar RF
performance.
Figure 17. Application of receiver with IF Balun
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. However,
when direct conversion is used (IF = DC), a so-called
phenomenon DC-offset could occur at the two IF
outputs. In most practical applications, IF should be
more than a few hundreds kHz to avoid DC-offset cor-
rection.
Refer the Absolute Maximum Ratings table for allowed
DC and thermal condition.
