WCDMA Quasi-Direct Modulator  
with VGA and PA Driver  
MAX2395  
General Description  
Features  
The MAX2395 fully monolithic quasi-direct modulator IC  
is designed for use in WCDMA/UMTS transmitters. The  
quasi-direct modulation architecture reduces system  
cost, component count, and board space compared to  
transmitters using an IF SAW filter with IF VCO and IF  
synthesizer blocks.  
o 5% EVM for P  
= +6dBm  
OUT  
o 1920MHz to 1980MHz Operation  
o +2.7V to +3.3V Single-Supply Operation  
o +6dBm Output Power at 72mA  
o 81dB Minimum Automatic Gain-Control (AGC)  
The MAX2395 includes I/Q baseband filters, an IF I/Q  
modulator with VGA, a fully monolithic VCO with PLL,  
an upconverter mixer, an RF VGA, and a power amplifi-  
er (PA) driver. The use of the quasi-direct modulator  
scheme ensures 5% (typ) EVM and a 30dB (min) carri-  
er suppression. The RF VGA and IF VGA provide a  
nominal 90dB of output power control. No external local  
oscillators are required, enabling efficient implementa-  
tion of variable duplex offset systems.

Consumption  
o No IF SAW Filter Necessary  
o On-Chip RF PLL, with Fully Monolithic VCO  
o Ultra-Low External Component Count  
The PLL is programmed by loading data on the SPI™/  
MICROWIRE™-compatible 3-wire serial bus. The IC  
operates from a single +2.7V to +3.3V supply. The  
devices are available in space-saving 28-pin QFN and  
thin QFN exposed-pad packages (5mm x 5mm).
