Applications Information
The circuit shown in
Figure 1 is recommended as a starting
point for portable radio designs Loopstick antenna L1 is
used in place of L0 and the RF amplifier is used with a
resistor load to drive the mixer A double tuned circuit at the
output of the mixer provides selectivity while the remainder
of the gain is provided by the IF section which is matched to
the diode through a unity turns ratio transformer RAGC may
be used in place of CAGC to bypass the internal AGC detec-
tor and provide more recovered audio
An AM automobile radio design is shown in
Figure 2 Tuning
of both the input and the output of the RF amplifier and the
mixer is accomplished with variable inductors Better selec-
tivity is obtained through the use of double tuned interstage
transformers Input circuits are inductively tuned to prevent
microphonics and provide a linear tuning motion to facilitate
push-button operation
Coil specifications for
Figure 1 are as follows
