Broadband RF gain blocks for high dynamic-range systems

May 30, 2013 // By Graham Prophet
Analog Devices has announced a series of RF amplifiers that offer an optimised combination of linearity, power, and noise figure performance over a wide frequency range.

The four RF amplifier gain blocks ease the design of high dynamic range communications, defence and instrumentation systems. Operating over a frequency range of 30 MHz to 6 GHz, the ADL5544, ADL5545, ADL5610 and ADL5611 RF amplifiers offer an optimal 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.

The four single-ended RF amplifiers feature excellent OIP3 and P1dB noise figure specifications over a wide frequency range and are internally matched to 50Ω 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.

Pricing is from $1.35 to $1.99 (1000).
