... Electrostatic sensitive device. Observe precautions for handling. 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 option, output level and spurious products are adjustable at pins 19 and 20. In conjunction with Atmel’ ...
