The AD6684 is a 135 MHz bandwidth, quad intermediate frequency (IF) receiver. It consists of four 14-bit, 500 MSPS ADCs and various digital processing blocks consisting of four wideband DDCs, an NSR, and VDR monitoring. The device has an on-chip buffer and a sample-and-hold circuit designed for low power, small size, and ease of use. This device is designed to support communications applications. The analog full power bandwidth of the device is 1.4 GHz. The quad ADC cores feature a multistage, differential pipelined architecture with integrated output error correction logic. Each ADC features wide bandwidth inputs supporting a variety of user-selectable input ranges. An integrated voltage reference eases design considerations. The AD6684 is optimized for wide input bandwidth, excellent linearity, and low power in a small package. The analog inputs and clock signal input are differential. Each pair of ADC data outputs are internally connected to two DDCs through a crossbar mux. Each DDC consists of up to five cascaded signal processing stages: a 48-bit frequency translator, NCO, and up to four half-band decimation filters. Each ADC output is connected internally to an NSR block. The integrated NSR circuitry allows improved SNR performance in a smaller frequency band within the Nyquist bandwidth. The device supports two different output modes selectable via the serial port interface (SPI). With the NSR feature enabled, the outputs of the ADCs are processed such that the AD6684 supports enhanced SNR performance within a limited portion of the Nyquist bandwidth while maintaining a 9-bit output resolution. Each ADC output is also connected internally to a VDR block. This optional mode allows full dynamic range for defined input signals. Inputs that are within a defined mask (based on DPD applications) are passed unaltered. Inputs that violate this defined mask result in the reduction of the output resolution. With VDR, the dynamic range of the observation receiver is determined by a defined input frequency mask. For signals falling within the mask, the outputs are presented at the maximum resolution allowed. For signals exceeding defined power levels within this frequency mask, the output resolution is truncated. This mask is based on DPD applications andsupports tunable real IF sampling, and zero IF or complex IF receive architectures. Operation of the AD6684 in the DDC, NSR, and VDR modes is selectable via SPI-programmable profiles (the default mode is NSR at startup).In addition to the DDC blocks, the AD6684 has several functions that simplify the AGC function in the communications receiver. The programmable threshold detector allows monitoring of the incoming signal power using the fast detect output bits of the ADC. If the input signal level exceeds the programmable threshold, the fast detect indicator goes high. Because this threshold indicator has low latency, the user can quickly turn down the system gain to avoid an overrange condition at the ADC input. Users can configure each pair of IF receiver outputs onto either one or two lanes of Subclass 1 JESD204B-based high speed serialized outputs, depending on the decimation ratio and the acceptable lane rate of the receiving logic device. Multiple device synchronization is supported through the SYSREF±, SYNCINB±AB, and SYNCINB±CD input pins. The AD6684 has flexible power-down options that allow significant power savings when desired. All of these features can be programmed using the 1.8 V capable, 3-wire SPI. The AD6684 is available in a Pb-free, 72-lead LFCSP and is specified over the −40°C to +105°C junction temperature range. Product Highlights Low power consumption per channel. JESD204B lane rate support up to 15 Gbps. Wide full power bandwidth supports IF sampling of signals up to 1.4 GHz. Buffered inputs ease filter design and implementation. Four integrated wideband decimation filters and NCO blocks supporting multiband receivers. Programmable fast overrange detection.

The AD9371 is a highly integrated, wideband RF transceiveroffering dual channel transmitters and receivers, integrated synthesizers, and digital signal processing functions. The ICdelivers a versatile combination of high performance and low power consumption required by 3G/4G micro and macro BTSequipment in both FDD and TDD applications. The AD9371operates from 300 MHz to 6000 MHz, covering most of the licensed and unlicensed cellular bands. The IC supports receiver bandwidths up to 100 MHz. It also supports observation receiver and transmit synthesis bandwidths up to 250 MHz to accommodate digital correction algorithms.The transceiver consists of wideband direct conversion signalpaths with state-of-the-art noise figure and linearity. Each complete receiver and transmitter subsystem includes dc offset correction, quadrature error correction (QEC), and programmable digitalfilters, eliminating the need for these functions in the digitalbaseband. Several auxiliary functions such as an auxiliary analog-to-digital converter (ADC), auxiliary digital-to-analog converters (DACs), and general-purpose input/outputs (GPIOs) are integratedto provide additional monitoring and control capability.An observation receiver channel with two inputs is included to monitor each transmitter output and implement interference mitigation and calibration applications. This channel also connects to three sniffer receiver inputs that can monitor radio activity in different bands.The high speed JESD204B interface supports lane rates up to 6144 Mbps. Four lanes are dedicated to the transmitters and four lanes are dedicated to the receiver and observation receiver channels.The fully integrated phase-locked loops (PLLs) provide high performance, low power fractional-N frequency synthesis forthe transmitter, the receiver, the observation receiver, and theclock sections. Careful design and layout techniques provide theisolation demanded in high performance base station applications.All voltage controlled oscillator (VCO) and loop filter components are integrated to minimize the external component count. A 1.3 V supply is required to power the core of the AD9371, anda standard 4-wire serial port controls it. Other voltage supplies provide proper digital interface levels and optimize transmitterand auxiliary converter performance. The AD9371 is packaged in a12 mm × 12 mm, 196-ball chip scale ball grid array (CSP_BGA).Applications 3G/4G micro and macro base stations (BTS) 3G/4G multicarrier picocells  FDD and TDD active antenna systems  Microwave, nonline of sight (NLOS) backhaul systems

The ADA4961 is a high performance, BiCMOS RF digital gain amplifier (DGA), optimized for driving heavy loads out to 2.0 GHz and beyond. The device typically achieves −90 dBc IMD3 performance at 500 MHz and −85 dBc at 1.5 GHz. This RF performance allows GHz converters to achieve their optimum performance with minimal limitations of the driver amplifier or constraints on overall power that typically result from GaAs amplifiers. This device can easily drive 10-bit to 16-bit HS converters.For many receiver applications, antialias filter (AAF) designs can be simplified or not required.The ADA4961 has an internal differential input impedance of 100 Ω and a differential dynamic output impedance of 50 Ω, eliminating the need for external termination resistors. The digital adjustability provides for 1 dB resolution, thus optimizing the signal-to-noise ratio (SNR) for input levels spanning 21 dB.The ADA4961 is optimized for wideband, low distortion performance at frequencies up to 2 GHz. These attributes, together with wide gain adjustment and relatively low power, make the ADA4961 the amplifier of choice for many high speed applications, including IF, RF, and broadband applications where dynamic range at very high frequencies is critical.The ADA4961 is ideally suited for driving not only analog-to-digital converters (ADCs), but also mixers, pin diode attenuators, SAW filters, and multielement discrete devices. It is available in a 4 mm × 4 mm, 24-lead LFCSP and operates over a temperature range of −40°C to +85°C.
