NOTES:  
1. FL1 and FL2 are 455 kHz ceramic bandpass filters, which should  
have input and output impedances of 1.5 kΩ to 2.0 kΩ. Suggested  
part numbers are MuRata CFU455X or CFW455x – the ‘X’ suffix  
denotes bandwidth.  
4. C  
C1  
and C are RF coupling capacitors and should have ≤ 20 Ω  
C3  
impedance at the desired input and oscillator frequencies.  
5. C provides “light coupling” of the oscillator signal into the mixer,  
C2  
and should have a 3.0 kΩ to 5.0 kΩ impedance at the desired  
2. LC1 is a 455 kHz LC resonator. Recommended part numbers are  
Toko America RMC2A6597HM or 5SVLC–0637BGT (smaller).  
The evaluation board layout shown provides for use of either  
resonator. Ceramic discriminator elements cannot be used with  
the MC3374 due to their low input impedance. The damping  
resistor value can be raised to increase the recovered audio or  
lowered to increase the quadrature detector’s bandwidth and  
linearity – practical limits are approximately 27 kΩ to 75 kΩ.  
Typically the quadrature detector’s bandwidth should match the  
low IF filter’s bandwidth.  
local oscillator frequency.  
6. Capacitors labelled C are bypass capacitors and should have  
B
20 Ω impedance at the desired RF and local oscillator frequencies.  
7. The network of L1, C1 and C2 provides impedance matching of  
the mixer input (nominally 3.0 kΩ shunted by 9.0 pF) to 50 Ω at the  
desired RF/IF input frequency. This will allow for bench testing of  
the receiver from typical RF signal generators or radio service  
monitors, but additional or different matching will be required to  
maximize receiver sensitivity when used in conjunction with an  
antenna, RF preamplifier or mixer.  
3. The data buffer is set up as a low–pass filter with a corner  
frequency of approximately 200 Hz. The audio buffer is a  
bandpass filter with corner frequencies of 300 Hz and 3.0 kHz.  
The audio amplifier provides bass suppression.
