(pins 3, 4, and 5, respectively) provide the control inputs. The

SKY74092-11 provides the following control and test registers:

Technical Description

Bias Reference

 Mode Selection

 Gain Control

 Current Selection

LNA bias currents are derived from an on-chip bandgap voltage

reference. The voltage reference requires a 10 k external

resistor.

The SKY74092-11 supports two types of fixed-length data

transfers: 9-bit and 27-bit. Data is latched starting from the

second high-to-low transition on the CLK signal after LE goes

low. The first high-to-low transition of the CLK signal is ignored.

Cellular Band LNA

The cellular band LNA requires an off-chip matching network at

input and output terminals. The LNA is designed to provide a

low Noise Figure (NF) and high 3^rdorder Input Intercept Point

(IIP3) to achieve the maximum dynamic range.

Package and Handling Information

The cellular LNA has four gain steps to optimize gain, linearity,

and noise at various input signal levels: high gain, mid-gain,

bypass, and high attenuation.

Since the device package is sensitive to moisture absorption, it

is baked and vacuum packed before shipping. Instructions on

the shipping container label regarding exposure to moisture

after the container seal is broken must be followed. Otherwise,

problems related to moisture absorption may occur when the

part is subjected to high temperature during solder assembly.

PCS Band LNA

The PCS band LNA requires an off-chip matching network at

input and output terminals. The PCS LNA is designed to provide

a low NF and high IIP3 to achieve the maximum dynamic range.

The SKY74100 is rated to Moisture Sensitivity Level 3 (MSL3) at

260 C. It can be used for lead or lead-free soldering. For

additional information, refer to the Skyworks Application Note,

PCB Design & SMT Assembly/Rework Guidelines for RFLGA

Packages, document number 103147.

The PCS LNA has four gain steps to optimize gain, linearity, and

noise at various input signal levels: high gain, mid-gain, bypass,

and high attenuation.

Care must be taken when attaching this product, whether it is

done manually or in a production solder reflow environment.

Production quantities of this product are shipped in a standard

tape and reel format.

Serial Interface

A three-wire serial bus is used to control the operation mode,

gain, and current of the LNAs. The CLK, DATA, and LE signals
