简  介:Features Supply Voltage: 5V Low Power Consumption: 15 mA/5V Output Level and Spurious Products Adjustable (Optional) Excellent Sideband Suppression by Means of Duty Cycle Regeneration of the LO Input Signal Phase-control Loop for Precise 90° Phase Shifting Power-down Mode Low LO Input Level: -15 dBm 50- Single-ended LO and RF Port LO Frequency Range of 30 MHz to 300 MHz Benefits Low Current Consumption Few External Components Result in Cost and Board Space Saving Adjustment Free Hence Saves Time 300-MHz Quadrature Modulator U2793B Electrostatic sensitive device. Observe precautions for handling. 1. 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-converter up to 2 GHz can be realized. Figure 1-1.
