3µW Shutdown Mode o Flexible Power-Down Modes Compatible with MAX2510/MAX2511 IF Transceivers ________________General Description The MAX2411A performs the RF front-end transmit/ receive function in time-division-duplex (TDD) communication systems.
It operates over a wide frequency range and is optimized for RF frequencies around 1.
9GHz.
Applications include most popular cordless and PCS standards.
The MAX2411A includes a low-noise amplifier (LNA), a downconverter mixer, a local-oscillator buffer, an upconverter mixer, and a variable-gain power-amplifier (PA) driver in a low-cost, plastic surface-mount package.
The MAX2411A’s unique bidirectional, differential IF port reduces cost and component count by allowing the transmit and receive paths to share the same IF filter.
The LNA has a 2.
4dB typical noise figure and a -10dBm input third-order intercept point (IP3).
The downconverter mixer has a low 9.
2dB noise figure and 4dBm input IP3.
Image and local-oscillator filtering are implemented off-chip for maximum flexibility.
The PA driver amplifier has 15dB of gain, which can be reduced over a 35dB range.
Power consumption is only 60mW in receive mode and 90mW in transmit mode and drops to less than 3µW in shutdown mode.
For applications requiring separate, single-ended IF input and output ports, refer to the MAX2410 data sheet.
For applications requiring only a receive function, Maxim offers a low-cost downconverter with LNA (see the MAX2406...
