Low-Power EVFAOLLULAOTWIOSNDKAITTAMSAHNEUEATL Cellular Upconverter-Driver
General Description
The 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 3✕4 ultra-chipscale package (UCSP).
