Figure 1a. ML13135 Test Circuit

The recovered audio measurements for the ML13135 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 dis-

criminator. See Figures 10 and 11 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

Ω 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 ana-

lyzer system. The first mixer input impedance was measured at

the pin with a network analyzer.
