These pins are DC coupled
and matched to 50 Ohms.
8
MIXERS - DOWNCONVERTERS - SMT
8 - 75
2, 4, 6, 8, 10, 12,
14, 16, 18, 20, 22,
24, 26, 28
GND
Backside of package has exposed metal ground slug
that must also be connected to ground.
3
Vdd
Power supply for the second stage LO amplifier. One
external bypass capacitor (1,000 pF) is required.
5, 15, 19
N/C
No connection. These pins may be connected to RF
ground. Performance will not be affected.
9, 27
MIX IF2,
MIX IF1
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).
11, 25
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).
13, 23
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).
17
LO
These pins are AC coupled
and matched to 50 Ohms.
21
Vdd LO
Bias voltage for the first stage of the LO amplifier. A
pull up inductor, resistor, and bypass capacitors are
required. (See application circuit).
