ADI Introduces Variable Gain Amplifiers

September 27, 2010

Analog Devices Inc. (ADI), a leader in high performance semiconductors for signal-processing applications and RF integrated circuits, introduced a series of highly integrated RF/IF variable gain amplifiers (VGA). ADI’s new ADL5201, ADL5202, ADL5240 and ADL5243 variable gain amplifiers offer breakthrough levels of integration—combining up to four discrete RF/IF blocks into a single device. With this unprecedented level of integration, radio system manufacturers can realize a significant reduction in component count and a major savings in bill of materials (BOM) cost. In addition to unsurpassed integration, the new VGAs offer industry-leading performance, linearity and flexibility that make them well-suited for demanding applications, such as cellular base stations, industrial/instrumentation and defense equipment.

“These new RF/IF variable gain amplifiers further expand ADI’s commitment to offering best-in-class levels of integration and performance for both RF and IF applications,” said Peter Real, Vice President, Linear and RF products, Analog Devices. “Both product families provide the user with flexibility to select their preferred parallel or serial formats, and offer fine 0.5 dB digital gain steps. This approach simplifies and eases system design, decreases footprint and enables designers of equipment such as next generation base stations to reduce component count, board area, supply lines and cost.”
