LNA and Mixer

Figure 9-22 LNA and mixer circuit

The LNA is a cascode configuration around transistor 7601.
This circuit provides gain with a low noise figure, while
providing isolation from the oscillator to antenna. This isolation
is necessary to comply with the legal requirements for radiated
interference.
The output of the LNA and the LO signal is mixed in transistor
7602. This is a one transistor mixer that provides high
conversion gain with low LO input signal. This level is only
around 20 mV. The reason for this high conversion gain is that
there is a 10.7 MHz trap at the base (5605 - 2610).
The output of the mixer is a tuned circuit at 10.7 MHz. The coil
is pre-aligned at the factory.
