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. Inde-

pendent 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 packaged in a

4mmx4mm, 20-pin, plastic leadless chip carrier.
