Product Description

The RF2483 is a dual-band direct I/Q to RF modulator designed for handset applications where multiple modes of operation are required. ‘The device provides common differential I/Q inputs and a common AGC amplifier. Independent single-ended LO inputs and single-ended high and low band RF outputs are provided. The device achieves a very low out-of-band noise density of -156dBm/Hz minimizing RF filtering. Operating from a single 2.7V supply, the device is assembled in a 4mm x 4mm, 20-pin, QFN package.
