DATA SHEET  
SKY42053: 700 – 1000 MHz High Dynamic Range, Diversity  
Receiver Front End  
Applications  
Description  
Skyworks SKY42053 is an integrated, high-dynamic range, low-  
noise receiver down converter for two-channel diversity systems.  
The device is fabricated using Skyworks highly reliable GaAs  
Metal Semiconductor Field-Effect Transistor (MESFET)  
technology.  
Cellular and GSM communications  
Mobile radio systems  
Paging  
Industrial, Scientific, Medical (ISM) band  
The SKY42053 includes a Low Noise Amplifier (LNA), followed by  
a double-balanced active mixer. Dual Local Oscillator (LO) inputs  
are selected using an external switch interface. The internal  
attenuator is integrated with the LNA. The attenuator function is  
also controlled using an externally controlled CMOS-compatible  
interface.  
Features  
High IIP3 mixer and LNA  
Wideband RF input frequency range (700 to 1000 MHz)  
Single or two-channel applications  
Use with LNA-mixer cascaded or mixer-only  
Bias selectable LNA/mixer functions  
Integrated solid state attenuator  
CMOS-compatible control interfaces  
• ±5 V supply operation  
Figure 1 shows a functional block diagram for the SKY42053. The  
24-pin, 11 x 11 mm Plastic Quad Flat Pack (PQFP) device  
package and pinout are shown in Figure 2. Signal pin  
assignments and functional pin descriptions are provided in  
Table 1.  
Operating range of –40 °C to +85 °C  
Supports frequency hopping applications
