New RF amplifiers offer industry's best combination of linearity, power, and noise figure performance over a wide frequency range.
Analog Devices, Inc. (ADI), a world leader in high-performance semiconductors for signal processing applications and RF ICs, today introduced four new RF amplifier gain blocks which ease the design of high dynamic range communications, defense and instrumentation systems. Operating over a frequency range of 30 MHz to 6 GHz, the ADL5544, ADL5545, ADL5610 and ADL5611 RF amplifiers offer the industry's best combination of linearity, gain and noise figure performance, enabling high performance with low power consumption. These devices complement Analog Devices' existing family of high performance RF/IF amplifiers by providing additional power vs. performance options and will be showcased at ADI's booth at the upcoming International Microwave Symposium.
The ADL5544, ADL5545, ADL5610 and ADL5611 single-ended RF amplifiers feature excellent OIP3 and P1dB noise figure specifications over a wide frequency range and are internally matched to 50 Ω at the input and output. In addition, they offer bill of materials savings as the only external components required are coupling/decoupling capacitors and a dc bias inductor. The new gain blocks are available in a SOT-89 package, making it easy to drop into any existing design for evaluation, feature an integrated on-chip bias circuit and are Class 1C (±1.5 kV ESD) rated.
