U2893B
Modulation PLL for GSM, DCS and PCS Systems
Description
The U2893B is a monolithic integrated circuit. It is realized using TEMIC’s advanced silicon bipolar UHF5S technology. The device integrates a mixer, an I/Q modulator, a phase-frequency detector (PFD) with two synchronous-programmable dividers, and a charge pump. The U2893B is designed for cellul...
