May 30, 2013 – Analog Devices ( www.analog.com , NASDAQ: ADI), a global leader in high-performance semiconductors for signal processing applications and radio frequency integrated circuits (RF ICs), today announced four new RF amplifier gain blocks that facilitate the design of high dynamic range communications, defense, and industrial systems. The new ADL5544, ADL5545, ADL5610, and ADL5611 RF amplifiers, covering a wide frequency range from 30 MHz to 6 GHz, feature industry-leading linearity, gain, and low noise characteristics, delivering exceptional performance while reducing power consumption. These new products complement ADI's existing high-performance RF/IF amplifier products by providing additional power-to-performance options, creating a more complete product portfolio. They will be showcased at the ADI booth at the International Microwave Symposium in Seattle, USA, this coming June.
The ADL5544, ADL5545, ADL5610, and ADL5611 single-ended RF amplifiers feature the best OIP3 and P1dB noise levels over a wide frequency range, with input and output matched to 50 Ω. Additionally, only coupling/decoupling capacitors and DC bias inductors are required as additional external components, which helps reduce the bill of materials (BOM). The new gain blocks are provided in an SOT-89 package, so they can be easily combined and evaluated in any existing design, and they support one on-chip bias circuit and are rated Class 1C (+1.5kv ESD).

The new RF amplifiers can be used with ADI's various IC products to easily configure signal chains from antenna to bit and from bit to antenna. For transmitter design, it is recommended to use the ADL5544 and ADL5545 with I/Q modulators such as the ADL5385, AD8345, AD8346, and AD8349, and the ADL5801 RF mixer. The ADL5610 and ADL5611 are effective when used with the ADL5521 low-noise amplifier (LNA), the ADL5801 RF mixer, and the ADL5380 demodulator.
