7.3 FM mixer 2
Table 3.
The FM quadrature mixer converts FM RF (65 MHz to 108 MHz and 162.4 MHz to
162.55 MHz) to an IF of 10.7 MHz. The FM mixer provides inherent image rejection and a
large dynamic range. The image rejection can be switched from low injection LO to high
injection LO via the I
increased by 6 dB via the I
AGC detection at the FM front-end mixer input with programmable threshold. When the
threshold is exceeded, the PIN diode drive circuit sources a current to an external PIN
diode circuit, keeping the mixer input signal level constant.
Keyed AGC function is selectable via the I
derived from the limiter level detector.
The AGC PIN diode drive circuit can be forced via the I
a local function for search tuning. In AM mode, the AGC PIN diode drive circuit can also
be forced via the I
diode circuitry. AGC information is available via the I
The FM quadrature mixer converts 10.7 MHz FM IF1 to 450 kHz FM IF2 and includes
inherent image rejection. The gain can be selected via I
ceramic filter insertion loss.
