RF2483
LOW NOISE DUAL-BAND QUADRATURE
MODULATOR WITH AGC
The RF2483 is a dual-band direct I/Q to RF modulator designed for hand-
set applications where multiple modes of operation are required. The
device provides common differential I/Q inputs and a common AGC ampli-
fier. 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 4mmx4mm, 20-pin, QFN
package.
