Description

RF Input

Input

RF input.

The GPS RF input signal @ 1575.42MHz from an external

antenna with LNA and filter is connected to this pin via an

input-matching network (see fig.4).

N/C

Not connected. (See Note 4)

O/P 1-

Output

Stage 1 mixer output @ 175.42MHz - inverse phase.

One of a balanced output from first stage IF mixer, to which

one input of an external balanced 175MHz bandpass filter is

connected. External dc biasing is required via an inductor

connected to VCC(RF) - the value of which is dependent on the

filter used.

O/P 1+

Output

Stage 1 mixer output @ 175.42MHz - true phase.

Second of a balanced output from first stage IF mixer, to which

the second input of an external balanced 175MHz bandpass

filter is connected. External dc biasing is required via an

inductor connected to VCC(RF) - the value of which is dependent

on the filter used.

VCC (2)

Input

Positive supply to the Stage 2 IF mixer.

I/P 2-

Input

Stage 2 mixer input @ 175.42MHz - inverse phase.

One of a balanced input to the second stage IF mixer, to which

one of the balanced signal outputs from the external 175MHz

bandpass filter is connected.

I/P 2+

Input

Stage 2 mixer input @ 175.42MHz - true phase.

Second of a balanced input to the second stage IF mixer, to

which the second of the balanced signal outputs from the

external 175MHz bandpass filter is connected.

42, 43

VEE (IF)

Input

Negative supply to the Stage 2 IF mixer, and Stage 3 IF block.

O/P 2-

Output

Stage 2 mixer output @ 35.42MHz - inverse phase.

One of a balanced output from second stage IF mixer, to which

one input of an external balanced 35.42MHz bandpass filter is

connected. External dc biasing is required via an Inductor

connected to VCC. (See Note 3)

O/P 2+

Output

Stage 2 mixer output @ 35.42MHz - true phase.

Second of a balanced output from second stage IF mixer, to

which the second input of an external balanced 35.42MHz

bandpass filter is connected. External dc biasing is required

via an Inductor connected to VCC. (See Note 3)

VCC (3)

Input

Positive supply to the Stage 3 IF mixer.

I/P 3-

Input

Stage 3 mixer input @ 35.42MHz - inverse phase.

One of a balanced input to the third stage IF mixer, to which

one of the balanced signal outputs from the external 35.42MHz

bandpass filter is connected. (See Note 3)

I/P 3+

Input

Stage 3 mixer input @ 35.42MHz - true phase.

Second of a balanced input to the third stage IF mixer, to which

the second of the balanced signal outputs from the external

35.42MHz bandpass filter is connected. (See Note 3)
