These pins and the ground paddle should be
connected to a high quality RF/DC ground.
GND
LO inputs. Need DC decoupling capacitors.
The ports could be driven single ended or differentially.
3, 4
LOP, LON
10
Q channel differential baseband input. These high
impedance ports should be biased around 1.5V DC.
Nominal recommended baseband input is around
1.6V pp differential.
9, 10
QN, QP
DC coupled and matched to 50 Ohms,
output requires blocking capacitor.
16
RFOUT
Supply voltage for the mixer and
output stages 79mA @ +5.0V.
18
21, 22
24
Vcc1
IP, IN
Vcc2
I channel differential baseband input.
These high impedance ports should be at the
same bias voltage (VbbDC) as Qn & Qp.
Supply voltage for the LO stage 88mA @ +5.0V.
