Low-Power Cellular Upconverter-Driver
Features
o Ultra-Small Implementation Size o Low Off-Chip Component Count o 15mA at -15dBm POUT o 34mA at +6.5dBm POUT and -53dBc ACPR o <1µA Shutdown Mode o Separate Shutdown for LO Buffer o No External Logic Interface Circuitry Required
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 I S M 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 f r e q u e n c y 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 ultrasmall 34 ultra-chipscale package (UCSP).

Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
