AD61009ARS

Low Power Mixer 3 V Receiver IF Subsystem

Analog Devices 

In operation (Figure 15), the AD61009 evaluation board draws

about 8.5 mA at midgain (59 dB). Use high impedance probes

to monitor signals from the demodulated I and Q outputs and

the IF output. The MGC voltage should be set such that the

signal level at DMIP does not exceed ± 150 mV; signal levels

AD61009

above this will overload the I and Q demodulators. The inser-

tion loss between IFOP and DMIP is typically 3 dB if a simple

low-pass filter (R8 and C2) is used and higher if a reverse-

terminated bandpass filter is used.
