1.2

RF input pin of mixer. This

mixer is designed as double

balanced type.

This pin should be externally

coupled to front stage with DC cut

capacitor.

−

Ground pin. This pin must be

5

connected to the system ground.

Form the ground pattern as wide

as possible and the truck length

as short as possible to minimize

ground impedance.

Supply voltage pin.

1

This pin should be connected with

bypass capacitor (example: 1 000

pf) to minimize ground

impedance.

−

IF output pin. This output is

configured with open collector of

high impedance. This pin should

be externally equipped with

matching circuit of inductor should

be selected as small resistance

and high frequency use.

3 LOinput

1.4

Input pin of local amplifier. This

amplifier is designed as differen-

tial type.

This pin should be externally

coupled to local signal source

with DC cut capacitor.
