Description
Interface Schematic
2/26/1997
Balanced IF input pin. This pin is internally DC-biased and should be
DC-blocked if connected to a device with a DC level present. For singleended input operation, one pin is used as an input and the other IF
input is AC-coupled to ground. The single-ended input impedance is
50Ω.
Same as pin 1, except complementary input.
Ground connection. For best performance, keep traces physically short
and connect immediately to ground plane.
Single-ended LO input pin. This pin is internally DC-biased and should
be DC-blocked if connected to a device with a DC level present. The
single-ended input impedance is 50Ω.
Same as pin 3, except complementary input.
RF Output Pin. The output impedance is 50Ω.
This pin requires a small inductance to ground to optimize the gain and
third order intercept point. See Evaluation Board Layout. The trace
length on the board is approximately 65mils.
Same as pin 7.

MIXERS
Power down control. When logic “high” (between 1.2V and 1.8V) the
device is active and all circuits are operating. When logic “low”
(between 0.0V and 0.6V) the device is inactive and all circuits are
turned off.
Supply Voltage pin. External bypassing is required. External RF, LO,
and IF bypassing is required. The trace length between the pin and the
bypass capacitors should be minimized. The ground side of the bypass
capacitors should connect immediately to ground plane.
