MAX2510 19-1296 Rev 2 1/01 Low-Voltage IF Transceiver with Limiter/RSSI and Quadrature Modulator General Description Features The MAX2510 is a highly integrated IF transceiver for +2.7V to +5.5V Single-Supply Operation digital wireless applications. It operates from a +2.7V to Complete Receive Path: 600MHz (max) 1st IF to +5.5V supply voltage and features four operating 30MHz (max) 2nd IF modes for advanced system power management. Supply current is reduced to 0.2A in shutdown mode. Unique, Wide-Dynamic-Range Downconverter In a typical application, the receiver downconverts a Mixer Offers -8dBm IIP3, 11dB NF high IF/RF (up to 600MHz) to a low IF (up to 30MHz) 90dB Dynamic-Range Limiter with High-Accuracy using a double-balanced mixer. Additional functions RSSI Function included in the receiver section are an IF buffer that can drive an off-chip filter, an on-chip limiting amplifier Differential Limiter Output Directly Drives offering 90dB of received-signal-strength indication CMOS Input (RSSI), and a robust differential limiter output driver 100MHz to 600MHz Transmit Quadrature designed to directly drive a CMOS input. The transmit- Modulator with 41dB Sideband Suppression ter section upconverts I and Q baseband signals to an IF in the 100MHz to 600MHz range using a quadrature 40dB Transmit Gain-Control Range Up to +1dBm modulator. The transmit output is easily matched to Output Power drive a SAW filter with an adjustable output from 0dBm Advanced Power Management (four modes) to -40dBm and excellent linearity. The MAX2511 has features similar to the MAX2510, but 0.2A Shutdown Supply Current upconverts a low IF with an image-reject mixer. The MAX2511 downconverter also offers image rejection with a limiter/RSSI stage similar to that of the MAX2510. Ordering Information PART TEMP.
