13. The variations (especially in case of small coupling coefficient) in the oscilation coil may cause a parasitic oscillation of
approximately 100 MHz to occur at the local oscillation buffer output (pin 20) at low temperatures. In this case, connect a
capacitor of 30 pF or greater across pin 20 and GND. (When the oscillation coil is used with no tap, no problem arises.)
14. The recommended double-tuning circuit has a loose coupling at 2T. Therefore, the change in the total number of turns may
affect the coupling coefficient subtly, causing a tight coupling and making the selectivity characteristic double-humped.
Especially for a receiving band of 1400 kHz or more, the tracking method may affect the band characteristic of sensitivity
and the cross modulation characteristic considerably. When making a design, check to see if critical coupling occurs or not.
15. Sensitivity difference at 600 kHz or less
In the application circuit configuration shown below, the bypass capacitor in the position where the tuning voltage is applied
and coupling L for double-tuning may cause an antiresonance point of 400 kHz to 600 kHz depending on the variations in
the coil, varactor diode, etc. The value of the bypass must be 0.047 μF or greater. The recommended value is 0.1 μF.
