Low-Cost RF Up/Downconverter
with LNA and PA Driver
________________General Description
The MAX2411A performs the RF front-end transmit/
receive function in time-division-duplex (TDD) communi-
cation 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 trans-
mit 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 downconvert-
er 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
