Analog Devices unveils RF and microwave innovations at IMS2013

USA: Analog Devices Inc. (ADI) introduced three RF and microwave ICs designed for high-performance transmitters and receivers used in high-dynamic-range applications, such as wireless infrastructure, defense systems, industrial, microwave point-to-point radios and more.

The new products offer breakthrough performance and expand ADI’s portfolio of more than 1,000 high-performance RF ICs covering the entire signal chain, from antenna to bits and back. Featured in Booth #2411 at the International Microwave Symposium in Seattle, Wash., June 2-7, the new devices include:

Incorporating ADI’s leading high-performance broadband power detection technology, the ADL6010 microwave power detector offers unprecedented linearity and stability over temperature. Unlike alternative devices based on commonly used non-linear and non-temperature-stable Schottky diodes, the ADL6010 features a simple, proprietary linearization 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 linearization system achieves leading accuracy and improves the temperature performance to ±0.5 dB over the range of -40°C to +85°C. The ADL6010 microwave detector is accurate from 500 MHz to 40 GHz, has a 50-ohm 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. The device integrates a 700 MHz to 2.7 GHz wideband synthesizer, an active mixer, a high-dynamic-range digital VGA, RF DSA, 4:1 RF input switch, RF balun and LDO.

The ADRF6620 offers significant bill of material savings while maintaining low noise and high linearity performance. The 4:1 RF input switch makes the ADRF6620 ideal for DPD receivers in MIMO infrastructure applications. With an OIP3 of up to 44 dBm from RF input to DGA output, the ADRF6620 is well suited for high-performance UMTS, LTE-A and MC-GSM DPD applications.

Designed for new 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 significant 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 new 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.
