RECEIVING AND TRANSMITTING
Selecting the IF filter shape (Continued)
• SHARP
This selection is to emphasize the passband width of
the filter. The filter has an almost ideal shape factor.
Signals of the out of passband are extremely filtered
out and it gives you better audio quality.
• SOFT
The filter shoulders are roundly formed as in analog
filters. This decreases noise components in the
high and low frequencies of the filter passband
and increases the S/N of the target signal. These
characteristics play an effective role in picking up
very weak signals in the 50 MHz band, for example.
The shape factor is kept, and the sharpness of the
bandpass is excellent.

IP Plus function

The IP Plus function improves the Intermodulation
Distortion (IMD) quality by exerting the direct sampling
system performance.
This function optimizes the Analog/Digital Converter
(ADC) against the distortion when you receive a
strong input signal. It also improves the Third-order
Intercept Point (IP3) while minimizing the reduction of
the receive sensitivity.
