Abstract :
A chip set for compact transceivers meeting IS54 dual-mode cellular telephone standards is described. It consists of a direct up-conversion modulator and a double conversion receiver in a 12-GHz super-self-aligned bipolar process. It is operated from a 5-V power supply, and the total power dissipation is 310 mW. Both circuits can be put into a power-down mode with a maximum off-current of 10 mu A. The modulator chip is 4.1 mm/sup 2/, and the receiver chip is 4.9 mm/sup 2/.<>
