The AD9355 is a dual-receiver, single-transmitter radio frequency (RF) transceiver that supports the IEEE 802.16 WiMAX/WiBro standard. It has a bandwidth of 3.5 MHz to 10 MHz, a receiver sensitivity of up to NF<3.5 dB, and a transmit power control range of 58 dB with a resolution of 0.25 dB.
The AD9355 is a single‑transmitter, dual‑receiver RF transceiver designed for WiMAX/WiBro applications. It integrates high‑performance ADCs and DACs, offers a JESD‑207 digital interface, and provides features such as automatic gain control, low noise figure, and high linearity.
The device operates from 3.3 GHz to 3.8 GHz, supports bandwidths between 3.5 MHz and 10 MHz, and includes an internal fractional‑N synthesizer with 10 Hz LO steps. It is supplied from a 3.3 V single or dual supply, contains on‑chip LDO regulators, and is packaged in an 8 mm × 8 mm, 56‑lead LFCSP.
