MOTOROLA RF/IF DEVICE DATA
Although the MC13136 can be operated with a ceramic
discriminator, the recovered audio measurements for both
the MC13135 and MC13136 are made with an LC quadrature
detector. The typical recovered audio will depend on the
external circuit; either the Q of the quad coil, or the RC
matching network for the ceramic discriminator. On the
MC13136, an external capacitor between Pins 13 and 14 can
be used with a quad coil for slightly higher recovered audio.
See Figures 10 through 13 for additional information.
Since adding a matching circuit to the RF input increases
the signal level to the mixer, the third order intercept (TOI)
point is better with an unmatched input (50
from Pin 21 to
Pin 22). Typical values for both have been included in the
Electrical Characterization Table. TOI measurements were
taken at the pins with a high impedance probe/spectrum
analyzer system. The first mixer input impedance was
measured at the pin with a network analyzer.
