The AD9355 is an RF transceiver with integrated ADCs and DACs, designed for IEEE 802.16 WiMAX/WiBro applications. It features dual receivers and a single transmitter, with an operating band of 3.3 GHz to 3.8 GHz. The receiver has superior sensitivity and the transmitter is highly linear and spectrally pure. The AD9355 also includes an integrated fractional-N synthesizer and an industry-standard JESD-207 digital interface.
The AD9355 is a single‑transmitter, dual‑receiver RF transceiver designed for WiMAX/WiBro applications. It integrates ADCs, DACs, an internal fractional‑N synthesizer and provides a JESD‑207 digital interface for easy connection to baseband ASICs or FPGAs.
Key features include an operating band of 3.3 GHz‑3.8 GHz, bandwidth from 3.5 MHz to 10 MHz, low noise figure (< 3.5 dB), Tx EVM of –38 dB, and a highly linear transmitter with sideband noise below –134 dBm/Hz at 22 MHz offset. The device is supplied from a 3.3 V source and packaged in an 8 mm × 8 mm, 56‑lead LFCSP.
