New RF and microwave chips from Analog Devices

26 June 2013 Telecoms, Datacoms, Wireless, IoT

Analog Devices has introduced three RF and microwave ICs designed for high-performance transmitters and receivers used in high-dynamic-range applications, such as wireless infrastructure, defence systems, industrial, microwave point-to-point radios and more.

Incorporating broadband power detection technology, the ADL6010 microwave power detector offers excellent linearity and stability over temperature. Unlike alternative devices based on commonly used non-linear and non-temperature-stable Schottky diodes, the IC features a simple, proprietary linearisation system that eliminates distortion due to source loading – an important benefit in applications where a low-ratio coupler is used to extract a sample of the primary signal.

The ADL6010’s linearisation system achieves high accuracy and improves the temperature performance to ±0,5 dB over the range of -40°C to +85°C. The chip is accurate from 500 MHz to 40 GHz, has a 50 Ω input impedance and an input range of -30 dBm to 15 dBm.

Designed for high performance digital pre-distortion (DPD) receivers, the ADRF6620 provides a full-featured solution in a compact form factor. It integrates a 700 MHz to 2,7 GHz wideband synthesiser, an active mixer, a high-dynamic-range digital VGA, RF DSA, 4:1 RF input switch, RF balun and LDO.

The ADRF6620’s 4:1 RF input switch makes it ideal for DPD receivers in MIMO infrastructure applications. With an OIP3 of up to 44 dBm from RF input to DGA output, the chip is well suited for high-performance UMTS, LTE-A and MC-GSM DPD applications.

Aimed at high-bandwidth microwave point-to-point receivers, the ADRF6518 is a high-dynamic-range, low-noise, dual-channel baseband VGA with dual 63 MHz programmable low-pass filters and dual power detectors. The device offers bill of materials savings by replacing discrete filters and amplifiers and replacing them with a highly integrated programmable bandwidth and gain device.

The ADRF6518 features excellent channel-to-channel match and flexible gain control, and can be used in receivers supporting up to 112 MHz channel bandwidth, as well as new E-Band receivers with up to 1 GHz of channel bandwidth. The VGA is capable of rejecting large out-of-band interferers while amplifying the desired signal, reducing the bandwidth and dynamic range requirements of the ADC.
