Description
Equivalent Circuit
31
CDMA_MIX_OUT–
CDMA differential cellular mixer open collector output. VCC pull up inductor is required, and
the output impedance is set by an external matching network.
32
CDMA_MIX_OUT+
CDMA differential cellular mixer open collector output. VCC pull up inductor is required, and
the output impedance is set by an external matching network.
33
AMPS_MIX_OUT–
AMPS differential mixer open collector output. VCC pull up inductor is required, and the output
impedance is set by an external matching network.
34
AMPS_MIX_OUT+
AMPS differential mixer open collector output. VCC pull up inductor is required, and the output
impedance is set by an external matching network.
35
PCS_MIXER_OUT–
PCS differential mixer open collector output. VCC pull up inductor is required, and the output
impedance is set by an external matching network.
36
PCS_MIXER_OUT+
PCS differential mixer open collector output. VCC pull up inductor is required, and the output
impedance is set by an external matching network.

37
VCC_MIX
Voltage supply for the mixers. RF bypass capacitor should be close to pin with minimal trace
length.
38
PCS_LO
The local oscillator input for the PCS band mixer.
39
CELL_LO
The local oscillator input for the cellular band mixer.
40
PCSMIX_BYPASS
Low frequency bypass for the PCS mixer. Typically, a 47 nF is connected from pin to ground.
41
PCS_MIX_IN
PCS mixer input. Requires AC coupling capacitor
42
CELL_MIX_IN
Cellular mixer input
43
RF_BIAS_RES
This sets the RF bias current. Typically, a 15 k
resistor is connected from the pin to ground.
44
CELL_LNA_BIAS_RES
This sets the cellular LNA bias current. Typically, 27 k
is connected to ground.
