The ADRV9003 from Analog Devices is an RF Transceiver that operates from 30 to 6000 MHz covering the UHF, VHF, industrial, scientific, medical (ISM) and cellular frequency bands. It has a single-channel transmitter and dual-channel receivers that can operate in both TDD and FDD modes. The transceiver includes DC offset correction, quadrature error correction (QEC), and programmable digital filters, which eliminate the need for these functions in the digital baseband. It also has several auxiliary functions, such as auxiliary analog-to-digital converter (ADCs), auxiliary digital-to-analog converters (DACs), and general-purpose inputs/outputs (GPIOs), to provide additional monitoring and control capability.
The transceiver has fully integrated phase-locked loops (PLLs) which provide high performance, low power, fractional-N frequency synthesis for the transmitter, receiver, and clock sections. Careful design and layout techniques provide the isolation required in high performance personal radio applications.
The ADRV9003 requires a DC supply of 1/1.3/1.8 V and can be controlled via standard 4-wire SPI, LVDS & CMOS synchronous serial interfaces. It has power saving techniques like low power monitor and sleep modes with support for fast frequency hopping and dynamic profile switching for dynamic data rates and sample rates. The transceiver supports high data rate and low data rate interfaces using configurable CMOS or low voltage differential signaling (LVDS) serial synchronous interface (SSI).
This transceiver is available in a 196-ball CSP/BGA package that measures 12 x 12 mm and is ideal for mission critical communications, very high frequency (VHF), ultrahigh frequency (UHF), cellular (up to 6 GHz), time division duplexing (TDD) and frequency division duplexing (FDD) applications.
