Pin Description
PIN
1
NAME
DEGEN
DESCRIPTION
LNA Degeneration. Connect a 1nH to 3nH inductor from DEGEN to ground.
2
R
LNA
LNA Bias. Connect an 18k
to 24k
resistor from R
LNA
to ground. Adjust R
LNA
to adjust the linearity
of the input LNA in the HGHL mode.

GND
LNAIN
MODE0
MODE1
MODE2
Ground. Connect to PC board ground plane using low-inductance vias.
RF Input. Requires a DC-blocking capacitor, which can be used as part of the matching network.
Logic Input. See Table 1.
Logic Input. See Table 1.
Logic Input. See Table 1.
8, 11, 14, 18,
24, 25, 27
N.C.
No Connection. These pins are internally unconnected. Connect to the PC board ground plane.
9
LO/2
Logic Input. Drive low to disable the LO/2. Drive high to enable the LO/2.
10
LO_IN
LO Input. Internally matched to 50
. Requires an external DC-blocking capacitor. The LO input
frequency can be internally divided by two prior to application to the mixer by driving LO/2 high.
12, 23
I.C.
Internally Connected. Leave these pins unconnected for proper operation.
13
LO_OUT
LO Buffer Output. Internally matched to 50
. Does not require a DC-blocking capacitor. The output
frequency of the buffer is equal to the LO frequency divided by two when LO/2 is high, or the LO
frequency when LO/2 is low.
15, 16, 26
V
CC
Power Supply. Bypass pins 16 and 26 to the PC board ground with a capacitor placed as close to the
pin as possible. Do not share capacitor ground vias with other ground connections.
17
BUFFEN
LO Output Buffer Enable. Drive high to enable the LO output buffer. Drive low to disable the LO
output buffer.
19, 20
IF_CDMA-,
IF_CDMA+
Differential IF Output Port. Requires pullup inductors to V
CC
, which can be used as part of the
matching network.
21
R
BIAS
Bias Resistor Connection. Connect an 18k
to 24k
resistor from R
BIAS
to ground. Adjust R
BIAS
to
adjust the linearity of the input LNA in all modes except HGHL and the mixer in all modes.
22
MIXIN
Mixer Input. Requires an external matching network
28
LNAOUT
LNA Output. Requires an external pullup inductor to V
CC
and a DC-blocking capacitor, both of which
can be used as part of the matching network.

EP
Exposed-Paddle Ground Connection. Solder the exposed paddle (EP) evenly to the board’s ground
plane for proper operation.
