1. Description
The IC U2793B is a 300-MHz quadrature modulator that uses Atmel
UHF process. It features low current consumption, single-ended RF ports and adjust-
ment-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-converter up to 2 GHz can be realized.
