Description
The IC U2793B is a 300-MHz quadrature modulator that uses Atmel‘s advanced UHF
process. It features low current consumption, single-ended RF ports and adjustment-
free application, which makes the device suitable for all digital radio systems, e.g.,
GSM, PCN, JDC and WLAN. As an option, output level and spurious products are
adjustable at pins 19 and 20. In conjunction with Atmel’s U2795B mixer, an up-con-
verter up to 2 GHz can be realized.
