900MHz Image-Reject Receivers  
with Transmit Mixer  
________________General Description  
____________________________Features  
ꢀ Receive Mixer with 35dB Image Rejection  
ꢀ Adjustable-Gain LNA  
The MAX2424/MAX2426 highly integrated front-end ICs  
provide the lowest cost solution for cordless and ISM-  
band radios operating in the 900MHz band. Both devices  
incorporate a receive image-reject mixer (to reduce filter  
cost) as well as a versatile transmit mixer. The devices  
operate from a +2.7V to +4.8V single power supply,  
allowing direct connection to a 3-cell battery stack.  
ꢀ Up to +2dBm Combined Receiver Input IP3  
ꢀ 4dB Combined Receiver Noise Figure  
ꢀ Optimized for Common Receiver IF Frequencies:  
10.7MHz (MAX2424)  
The receive path incorporates an adjustable-gain LNA  
and an image-reject downconverter with 35dB image  
suppression. These features yield excellent combined  
downconverter noise figure (4dB) and high linearity with  
an input third-order intercept point (IIP3) of up to +2dBm.  
70MHz (MAX2426)  
ꢀ PA Predriver Provides up to 0dBm  
ꢀ Low Current Consumption: 23mA Receive  
20mA Transmit  
The transmitter consists of a double-balanced mixer and  
a power amplifier (PA) predriver that produces up to  
0dBm (in some applications serving as the final power  
stage). It can be used in a variety of configurations,  
including BPSK modulation, direct VCO modulation, and  
transmitter upconversion. For devices featuring trans-  
mit as well as receive image rejection, refer to the  
MAX2420/MAX2421/MAX2422/MAX2460/MAX2463  
data sheet.

28 SSOP  
The MAX2424/MAX2426 have an on-chip local oscillator  
(LO), requiring only an external varactor-tuned LC tank  
for operation. The integrated divide-by-64/65 dual-mod-  
ulus prescaler can also be set to a direct mode, in which  
it acts as an LO buffer amplifier. Four separate power-  
down inputs can be used for system power manage-  
ment, including a 0.5µA shutdown mode.

___________________Pin Configuration  
The MAX2424/MAX2426 come in a 28-pin SSOP pack-  
age.
