REVISION HISTORY
The following table summarizes revisions to this document.
Revision
Date
Description
0
May 2008
• Initial Release of Data Sheet
1
Oct. 2008
• Corrected footnote reference in Typical Performances OFDM Signal -- 10 MHz Bandwidth table, p. 3
• Updated Fig. 13, MTTF versus Junction Temperature, to correct a calculation error, p. 9
2
Feb. 2010
• Modified VSWR rating to show the 3 dB overdrive capability, p. 1
• Corrected maximum input power level to the tested value, from 13 dBm to 25 dBm in Maximum Ratings
table, p. 2
• Fig. 3, Test Circuit Schematic, corrected Rogers RO4350B dielectric constant from 3.66 εr to 3.5 εr, p. 5
• Added AN3789, Clamping of High Power RF Transistors and RFICs in Over--Molded Plastic Packages to
Product Documentation, Application Notes, p. 24
3
Mar. 2011
• Table 1, Maximum Ratings, increased Input Power from 25 dBm to 30 dBm to reflect the true capability of
the device, p. 2
4
Oct. 2011
• Table 3, ESD Protection Characterization, removed the word “Minimum” after the ESD class rating. ESD
ratings are characterized during new product development but are not 100% tested during production. ESD
ratings provided in the data sheet are intended to be used as a guideline when handling ESD sensitive
devices, p. 2
• Fig. 5, Test Circuit Schematic, corrected pin connections for pin numbers 2, 3, 10 and 11 to reflect actual
pin functionality, p. 5
• Fig. 13, MTTF versus Junction Temperature removed, p. 9. Refer to the device’s MTTF Calculator
available at freescale.com/RFpower. Go to Design Resources > Software and Tools.
