Description

The SKY74100-11 receiver is a highly integrated device for tri-

band Code Division Multiple Access (CDMA) handsets with Global

Positioning System (GPS) capability. The SKY74100-11 supports

CDMA phones in the cellular CDMA, Personal Communications

System (PCS), and GPS modes.

The device requires a minimum number of external components

to complete a CDMA radio subsystem. Included within the

package are the downconverters, baseband filters with an auto-

tuning loop, UHF Voltage Controlled Oscillator (VCO), RF Phase

Locked Loop (PLL), and DC Offset Correction (DCOC). The

SKY74100-11 is designed to operate within a supply voltage

range of 2.7 V to 3.0 V.

External components needed for operation include matching

networks for differential mixer inputs and differential GPS Low

Noise Amplifier (LNA) inputs, CDMA/PCS Surface Acoustic Wave

(SAW) filters, three bias resistors for accurate bias control over

process variation, and two high tolerance load resistors for In-

Phase and Quadrature (I/Q) baseband output.

The SKY74100-11 output is a dual-channel, fully differential

analog signal at the baseband. Both channels maintain a

quadrature phase relationship with each other.

Together with the SKY74092 dual-band, tri-mode LNA, the

SKY74100-11 completes the receiver from the RF input to the I/Q

baseband outputs. The SKY74100-11 is fully compliant with the

E-911 standard and the advanced CDMA standard, Evolution Data

Only (1xEV-DO), Rev. 0.

A functional block diagram for the SKY74100-11 is shown in

Figure 1.
