MOTOROLA ANALOG IC DEVICE DATA
IF Amplifier
The first IF amplifier section is composed of three
differential stages. This section has internal dc feedback and
external input decoupling for improved symmetry and
stability. The total gain of the IF amplifier block is
approximately 42 dB at 455 kHz. Figure 8 shows the gain of
the IF amplifier as a function of the IF frequency.
The fixed internal input impedance is 1.5 k
; it is designed
for applications where a 455 kHz ceramic filter is used and no
external output matching is necessary since the filter requires
a 1.5 k
source and load impedance.
Overall RSSI linearity is dependent on having total
midband attenuation of 10 dB (4.0 dB insertion loss plus 6.0
dB impedance matching loss) for the filter. The output of the
IF amplifier is buffered and the impedance is 1.5 k
.
Limiter
The limiter section is similar to the IF amplifier section
except that six stages are used. The fixed internal input
impedance is 1.5 k
. The total gain of the limiting amplifier
section is approximately 96 dB. This IF limiting amplifier
section internally drives the quadrature detector section.
