U3770M  
CT2 I/Q Modulator and Clock Circuitry  
Description  
U3770M is a quadrature modulator realized with with TEMIC’s PLL IC U2783B and the GaAs front end  
MATRA MHS’ advanced 0.8 micron CMOS process. U7001BG, a complete CT2 chip set is available.  
The IC is especially designed for CT2 application  
in conjunction with TEMIC’s RF/IF signal processor  
Electrostatic sensitive device.  
Observe precautions for handling.
