Pin Number

Function

Description

Interface Schematic

1VccLO

Supply for LO Amplifier.

Draws approximately 120mA from VSLO.

2, 5, 8, 11,

14, 17, 20, 23

GND

These pins and the ground paddle should be

connected to a high quality RF/DC ground.

3

LOP

LO Input Port. This pin needs a DC blocking capacitor.

(Typical voltage on this pin will be 1.5 - 1.8V)

4LON

For single ended applications, this pin should be AC

grounded

6, 7, 12,

21, 22, 24

N/C

No Connection

9, 10

IFN, IFP

Differential baseband outputs, 400 ohm differential

output impedance. Each port should draw

approximately 25mA from VSIF without LO power and

28mA from VSIF with LO power on.

13, 18

CTRF

Center tap of the RF transformer. Biased at 2.2V when

connected to gound through a 91 ohm resistor.
