DCM Eyes Use In Multi-Mode Handsets

Designed for deployment in multi-mode handsets, the RF2483 direct-conversion modulator (DCM) features a noise floor of -157 dBm/Hz at a 20-MHz offset and a built-in, 35 dB gain-control function. The device exhibits a typical carrier and sideband suppression of greater than 40 dBc at maximum gain while maintaining a 50-MHz input bandwidth and an IP3 output of 19 dBm.
Other features include operation from a 2.7V power supply and an output frequency range of 700 Mhz to 1 Ghz and 1.7 Ghz to 2.2 Ghz. Samples and completely assembled evaluation boards are available now and production quantities of the device will appear in the second half of this year.
