W-CDMA Upconverter and PA Driver  
with Power Control  
General Description  
Features  
The MAX2383 upconverter and PA driver IC  
is designed for emerging ARIB (Japan) and  
ETSI-UMTS (Europe) W-CDMA applications. The IC  
includes an upconversion mixer with variable gain con-  
trol, an LO buffer, and a variable-gain PA driver for out-  
put power control.  
o +6dBm Output Power with -46dBc ACPR  
o Ultra-Miniature UCSP Package  
o Upconverter Gain-Control Range: 35dB  
o Automatic Dynamic Current Control  
o 12mA Quiescent Supply Current  
o On-Chip LO Buffer with Disable  
The MAX2383 is designed to support the IMT-2000  
frequency band. It includes a differential IF input port,  
an LO input port, and PA driver input/output ports. The  
upconverter mixer incorporates an AGC with over 30dB  
of gain control. The IC provides automatic throttle-back  
of PA driver and mixer current as output power is  
reduced. The main signal path and the LO buffer can  
be shutdown independently. The on-chip LO buffer can  
be kept ON while the main transmitter path is being  
turned on and off to minimize VCO pulling during TX  
gated-transmission.  
o Low Out-of-Band Noise Power in RX Band:  
≤ -144dBm/Hz at +6dBm P  
OUT  
o No Interstage TX SAW Bandpass Filter Required  
Ordering Information  
The MAX2383 is specified for +2.7V to +3.0V single  
supply and is housed in an ultra-miniature 3 x 4  
UCSP™ package for optimum cost- and space-reduc-  
tion and for best RF performance. The IC is targeted for  
the 2270MHz to 2580MHz LO frequency range. It is  
fabricated using an advanced high-frequency bipolar  
process. The mixer and PA driver linearity have been  
optimized to provide excellent RF performance in the  
1920MHz to 1980MHz band, while drawing minimal  
current. The mixer’s performance is optimized for a  
-10dBm 3dB LO drive at the LO buffer input port. The  
LO port can be configured to be driven either single-  
ended or differentially.

The MAX2383 achieves excellent noise and image sup-  
pression without the use of an interstage TX SAW band-  
pass filter, thereby saving valuable board space, cost,  
and supply current.
