GND
Description
Supply for LO Amplifier.
Draws approximately 120mA from VSLO.
These pins and the ground paddle should be
connected to a high quality RF/DC ground.
Interface Schematic
3
LOP
LO Input Port. This pin needs a DC blocking capacitor.
(Typical voltage on this pin will be 1.5 - 1.8V)
For single ended applications, this pin should be AC
4
LON
grounded
6, 7, 12,
N/C
21, 22, 24
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.
