Description
interface schematic
1, 6, 7, 11 - 14,
18, 20, 23
N/C
No connection. These pins may be connected to rF
ground. Performance will not be affected.
2, 5, 15, 17
GND
Package bottom must be
connected to rF/DC ground.
3
rF
This pin is matched single-ended 50 Ohm and DC
shorted to ground through a balun.
4
TAP
Center tap of secondary side of the internal rF balun.
short to ground with a zero ohm close to the iC.
8, 10, 24
Vcc1, Vcc2,
Vcc3
Power supply voltage. see application circuit
for required external components.
9
LO_BiAs
LO buffer current adjustment pin. Adjust the LO buffer
current through the external resistor r9 shown in the
application circuit (connect 270 Ohms for nominal
operation). This adjustment allows for a trade-off
between power dissipation and linearity performance of
the converter.
16
LO
This pin is matched single-ended 50 Ohm and DC
shorted to ground through a balun.
19
G_BiAs
external bias. see application circuit for recom-
mended external components. Apply +2.5V for nominal
operation at 5V supply voltage. G_Bias can be set to
between 0 and 5Vdc. The G_bias pin has an internal
15K ohm resistance to ground. This adjustment allows
for a trade off between conversion loss and linearity
performance of the converter (see figures CG, iP3 vs.
G-Bias).
21, 22
iFN, iFP
Differential iF input / output pins matched to differential
50 Ohms. For applications not requiring operation to
DC an off chip DC blocking capacitor should be used.
