GND
Ground. Connect to a solid ground plane.
74
LIM1_PE
Digital input control to enable the limiter amplifier 1. Enable logic level is High.
75
LIM1_V
CC
Limiter amplifier 1 supply pin. Use high quality decoupling capacitors right at the pin.
76
LIM1_Out-
Negative output of limiter amplifier 1. Requires AC coupling.
77
LIM1_Out+
Positive output of limiter amplifier 1. Requires AC coupling.
78
GND
Ground. Connect to a solid ground plane.
79
RSSI_RL1
Load resistor to ground. Nominal value is 6k
. This load is used to terminate the LIM RSSI current output and
maintain temperature and process variation to a minimum.
80
LIM1_RSSI
Current output of RSSI for the limiter amplifier 1. Connect in parallel with the RSSI output of the amplifier limiter 2
for cascaded response.
NOTES:
1. The HFA3726 generates a lower side band signal when the “I” input leads the “Q” input by 90 degrees.
2. For a reference LO frequency higher than a CW IF signal input, the “I” channel leads the “Q” channel by 90 degrees.
3. The in-phase reference LO transitions occur at the rising edges of the 2XLO signal. Quadrature LO transitions occur at the falling edges. 180
degrees phase ambiguity is expected for carrier locked systems without differential encoding.
