PRODUCT DESCRIPTION  
GSM to CDMA to AMPS. The clamping circuitry also main-  
tains the phase integrity of an overdriven signal. This allows  
phase demodulation of single carrier signals with an overrange  
signal.  
The AD6630 is an IF gain block designed to interface between  
SAW filters and differential input analog-to-digital converters.  
The AD6630 has a fixed gain of 24 dB and has been optimized  
for use with the AD6600 and AD6620 in digitizing narrowband  
IF carriers in the 70 MHz to 250 MHz range.  
While the AD6630 is optimized for use with the AD6600 Dual  
Channel, Gain Ranging ADC with RSSI, it can also be used in  
many other IF applications. The AD6630 is designed with an  
input impedance of 200 and an output of 400 . In the typi-  
cal application shown below, these values match the real portion  
of a typical SAW filter. Other devices can be matched using  
standard matching network techniques.  
Taking advantage of the differential nature of SAW filters, the  
AD6630 has been designed as a differential in/differential out  
gain block. This architecture allows 100 dB of adjacent channel  
blocking using low cost SAW filters. The AD6630 provides  
output limiting for ADC and SAW protection with Ͻ10° phase  
variation in recovery from overdrive situations.  
The AD6630 is built using Analog Devices’ high speed comple-  
mentary bipolar process. Units are available in a 300 mil SOIC  
(16 leads) plastic surface mount package and specified to operate  
over the industrial temperature range (–40°C to +85°C).  
Designed for “narrow-band” cellular/PCS receivers, the high  
linearity and low noise performance of the AD6630 allows for  
implementation in a wide range of applications ranging from
