Description
Interface Schematic
1, 4, 9, 12
GND
These pins and the ground paddle must be connected to a
high quality RF/DC ground.
2, 3
LOP, LON
Differential LO input ports. This device may be driven in
either differential or single ended mode. In single ended
mode, one port should be driven by the LO source while
the other port may be terminated with a 50
Ω
resistor to
ground. An external shunt 68
Ω
resistor is used to improve
VSWR, while an external 100 pF capacitor is required
to prevent DC supply voltage from appearing on the
customer’s PC board.
5
VB2
Bias Voltage for the LO stage. This voltage will affect the
Sideband Suppression, the Output Noise Floor and the
Power Consumption. The ideal voltage range for this port
is between +2.7 Vdc and +3.0 Vdc. The nominal current for
this port is 5.3 mA.
6, 7
Qn, Qp
Differential Quadrature baseband input. These are
high impedance ports. The nominal recommended bias
voltage is between 1.0 - 1.15V. The nominal recommended
baseband input voltage is 800 mV peak to peak differential.
By adjusting the DC bias voltage on ports Qn & Qp, the
Carrier Suppression of the device can be optimized for a
specific frequency band and LO power level. The typical
offset voltage for optimization is less than 5 mV.
The amplitude and phase difference between the I and Q
inputs can be adjusted in order to optimize the Sideband
Suppression for a specific frequency band
and LO power level.
8
VB1
Bias Voltage for the output stage. This voltage should be
connected to the Vcc supply. Nominal supply voltage is 3.3
Vdc. The nominal current for this port is 2.4 mA.
10
N/C
No connect.
11
RFP
RF Output port. This port is matched to 50
Ω
. A series
capacitor should be connected to this port in order to
prevent the DC supply voltage from appearing on the
customer’s PC board.
