REVISION HISTORY
The following table summarizes revisions to this document. Revision Date Description 0 Oct. 2010 • Initial Release of Data Sheet 1 Mar. 2011 • Added OIP3: 44.5 dBm @ 2140 MHz (W- -CDMA Application Circuit) to Features list, p. 1
- Typical CW Performance table: removed OIP3, p. 1
- Figs. 4 and 12, Test Circuit Component Layout, updated component part layout identifier to reflect package type. Changed from MMA20312B to QFN 3x3- -12B, p. 4, 8 1.1 Mar. 2011 • Updated device descriptor box to reflect W- -CDMAapplication circuit small- -signal gain value, p. 1 1.2 Feb. 2012 • All references to VCTRL in the data sheet tables, test circuitschematics and component layouts are replaced with VBIAS. VBIAS is the supply voltage which sets the internal bias conditions via pins 1, 2, and 12, p. 1- -3, 5- -7, 9. Footnote (1) VBIAS [Board] supplies VBA1,V BA2 and VBIAS [Device] added to test circuit component layouts, p. 4, 8.
