TEMIC U2896B Modulation PLL Datasheet
The U2896B 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 device is designed for cellular phones such as GSM900, DCS1800, and PCS1900, applying a transmitter architecture where the VCO operates at the TX output frequency, eliminating the need for a duplexer due to very low out-of-band noise.
