MAX2411A - Low-Cost RF Up/Downconverter

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.

19-1324; Rev 1; 2/98 EVAALVUAAILTAIOBNLEKIT Low-Cost RF Up/Downconverter with LNA and PA Driver MAX2411A ________________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.
