Interface Schematic
8
Power supply for the second stage LO amplifier. One
3
Vdd
external bypass capacitor (1,000 pF) is required.
61 mA typical, 73 mA maximum.

N/C
MIX IF2,
MIX IF1
No connection. These pins may be connected to RF
ground. Performance will not be affected.
IF output from the mixers. This pin is DC coupled to
the mixer. A low pass filter and blocking capacitor are
required between mixer IF port and IF amplifier.
(See application circuit).
AMP IF2,
AMP IF1
Inputs to the IF amplifiers. A low pass filter and block-
ing capacitor are required between mixer IF port and IF
amplifier. (See application circuit).
IF2, IF1
Outputs of the IF amplifiers and bias ports for the IF
amplifiers. A pull up inductor, resistor, and bypass
capacitors are required. (See application circuit).
IF1 = 71 mA typical, 85 mA maximum.
IF2 = 71 mA typical, 85 mA maximum.
17
LO
This pin is AC coupled and matched to 50 Ohms.
Bias voltage for the first stage of the LO amplifier. A
21
Vdd LO
pull up inductor, resistor, and bypass capacitors are
required. (See application circuit).
53 mA typical, 64 mA maximum.
