The MAX2510 is a highly integrated IF transceiver for  
digital wireless applications. It operates from a +2.7V to  
+ 5.5V s up p ly volta g e a nd fe a ture s four op e ra ting  
mod e s for a d va nc e d s ys te m p owe r ma na g e me nt.  
Supply current is reduced to 0.2µA in shutdown mode.  
+2.7V to +5.5V Single-Supply Operation  
Complete Receive Path: 600MHz (max) 1st IF to  
30MHz (max) 2nd IF  
Unique, Wide-Dynamic-Range Downconverter  
In a typical application, the receiver downconverts a  
high IF/RF (up to 600MHz) to a low IF (up to 30MHz)  
using a double-balanced mixer. Additional functions  
included in the receiver section are an IF buffer that  
can drive an off-chip filter, an on-chip limiting amplifier  
offering 90dB of received-signal-strength indication  
(RSSI), and a robust differential limiter output driver  
designed to directly drive a CMOS input. The transmit-  
ter section upconverts I and Q baseband signals to an  
IF in the 100MHz to 600MHz range using a quadrature  
modulator. The transmit output is easily matched to  
drive a SAW filter with an adjustable output from 0dBm  
to -40dBm and excellent linearity.

The MAX2511 has features similar to the MAX2510, but  
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.
