Description  
The SKY73013-306 contains a low noise amplifier at the RF  
input, the gain of which can be set to a high or low value via the  
gain control input. This LNA drives a highly linear quadrature  
mixer pair. The quadrature local oscillator signals to these mixer  
stages are provided by the 3/2 frequency conversion stage.  
The Skyworks SKY73013-306 is an integrated receiver down-  
converter subsystem for the 4.9–5.925 GHz band. Its exceptional  
dynamic range and quadrature accuracy make this device an  
ideal solution for direct conversion and low-IF OFDM and single-  
carrier communications systems (including 64-QAM WiMax  
and WLAN).  
The nominal supply voltage for SKY73013-306 is 3.3 V. This part  
can operate over the temperature range of -40 °C to 85 °C.  
The SKY73013-306 employs an innovative “no-pull” local  
oscillator (LO) architecture which offsets the required synthesizer  
frequency from that of the receiver center frequency by the  
non-integer factor of 3/2. This greatly improves the performance  
of direct conversion receiver architecture by eliminating dynamic  
DC offsets (caused by LO-RF leakage) and VCO pulling. This  
receiver frequency plan is compatible with the 3/2 “no-pull”  
modulator frequency plan.  
An evaluation board is available upon request.  
Skyworks offers lead (Pb)-free, RoHS (Restriction of  
Hazardous Substances)-compliant packaging.
