TEMIC U2893B Modulation PLL for GSM DCS PCS Systems handbook

Update: 28 September, 2023

The U2893B is a monolithic integrated circuit realized using TEMIC's advanced silicon bipolar UHF5S technology. It 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 cellular phones such as GSM, DCS1800, and PCS1900, applying a transmitter architecture where the VCO is operated at the TX output frequency. The U2893B exhibits low power consumption, and the power-down function extends battery life.
