Hi

have been examining some surplus mobile telephone base station
equipment and discovered that the 70MHz to 455kHz mixers consists of
2x SA602. Since I've never seen an application using two such items,
my guess it for an image rejection type mixer.


Could it be for dual diversity receive?

there are 4 receivers, two on each board (with 2x SA604 and 4x SA602),
so I think it is a lot of diversity if it was interesting
