Description
Equivalent Circuit
21
IF-LOin
–
1.3
IF input pin for the Pre-Mixer.
This pin is biased internally.
Capacitor should be connected in
series, and grounded through 51
.
21
24
GND
(Pre-Mix)
0
–
Ground pin for Pre-Mixer.
Connect to the ground with minimum
inductance.
Track length should be kept as short
as possible.
–––––––––––––
25
RF-LOin
–
2.3
RF input pin for the Pre-Mixer.
This pin is biased internally.
Capacitor should be connected in
series, and grounded through 51
.
25
26
V
CC
1
(Pre-Mix)
2.7 to 3.6
–
Supply voltage pin for the Pre-Mixer.
An internal regulator helps keep the
device stable against temperature or
V
CC
variation.
–––––––––––––
27
Pre-Mixout
2.7 to 3.6
–
Output from the Pre-Mixer. This pin
is designed as open collector. Due
to the high impedance output, this
pin should be externally equipped
with LC matching circuit to next
stage.
27
28
GND
(Modulator)
0
–
Ground pin for the modulator.
Connect to the ground with minimum
inductance.
Track length should be kept as short
as possible.
