TEMIC U2894B Modulation PLL for GSM DCS PCS Systems handbook

Update: 30 September, 2023

This document describes the features and characteristics of the U2894B monolithic integrated circuit (IC). The IC is designed for cellular phones such as GSM900, DCS1800, and PCS1900. It integrates a mixer, an I/Q modulator, a phase-frequency detector (PFD) with two synchronous programmable dividers, and a charge pump. The IC uses a transmitter architecture in which the VCO operates at the TX output frequency. No duplexer is needed since the out-of-band noise is very low. The U2894B exhibits low power consumption. Broadband operation gives you high flexibility for multi-band frequency mappings. The IC is available in a shrinked small-outline 28-pin package (SSO28). The U2893B offers the same functionality with other divider ratios. This IC is an electrostatic sensitive device. Observe precautions for handling.
