Low-Power, Cellular Upconverter-Driver
Low-Power, Cellular Upconverter Drives IC in Ultra-Chip-Scale Package
DescriptionThe MAX2307 is an integrated RF upconverter-driver optimized for the Japanese cellular frequency band. It can also be used for applications in the US cellular and ISM bands. Its low current consumption (15mA at -15dBm output) extends the average talk time.
The image rejection is done using only two external inductors at the upconverter output because the image frequency in Japanese cellular phones is typically 330MHz away. This realizes the image rejection with no current consumption penalty and only two inexpensive off-chip components, saving cost and valuable board space.
The MAX2307 has a separate shutdown control for the LO buffer to minimize VCO pulling. It comes in an ultra-small 3x4 ultra-chipscale package (UCSP).
