Information in using IC
1. Use the bias condition in “RF VCC
IF V CC “
2. Avoid coupling between the antenna tuning circuit and the local OSC.
3. Connect detection capacitor (C15) between pin13(output) and pin14(VCC ) so that no
leakage of the IF signal to the GND line occurs. If the capacitor C15 is connected to GND,
the S/N ratio and the usable sensitivity may get worse. Radiation from C15 may cause
harmonics in the IF signal to return to the RF stage, and the result may lead to more
tweet interference. So, connect C 15 as close to pin 13,14 as possible. Consider the
direction of the capacitor and separate it from the ANT circuit.
4. Use a semi-fixed resistor for R9 with VSM considered.
5. Consider the following conditions when designing the coils. The table is the input level
at each pin at which the detection output at fm =400Hz 30% mod becomes -25 dBm.

7. The L2 is used to remove the SW band.
If the RF stage is double-tuned, the difference in sensitivity within the RF band almost
disappears. thereby leading to worse spurious characteristic.

11. When using MW, no additional resistor is required
But when using LW(approximately 50℃ or greater), additionally connect a resistor of
27KΩ across pins 18 and 19 against increase in local OSC level.
12. For improvement in image frequency interference change the RF double tuning coil
as follows, and the image frequency interference becomes 63dB at fr = 1400KHz (Q
point of the tuning circuit must not be decreased with tuning resistor 100KΩ)
