Description

The U2730B-B is a monolithic integrated L-band downconverter circuit fabricated in TEMIC's advanced UHF5S technology. Combining the functionality of U2754B-B and U2755B-B in one integrated circuit, it covers all functions of an L-band down-converter in a DAB receiver. The U2730B-B includes a gain-controlled amplifier, a gain-controlled mixer, an output buffer, a gain-control block, an L-band oscillator and a complete frequency syntheziser unit. The frequency syntheziser block U2730B-B consists of an input buffer for the reference frequency signal, a reference divider, an LO divider, a tri-state phase detector, a loop filter amplifier, a lock detector, a programmable charge pump, a test interface and a control interface.

Electrostatic sensitive device. Observe precautions for handling.
