Differential RF/IF Amplifiers from Analog Devices Set New Distortion and Linearity Standards for Driving High Frequency ADCs

New ADL5561/62 amplifiers simplify drive for 12- to 16-bit analog-to-digital converters in advanced wire-line and wireless communications systems up to 500 MHz.
Visit Analog DevicesNORWOOD, Mass.--(EON: Enhanced Online News)-- Analog Devices, Inc. (NYSE: ADI), a global leader in high-performance semiconductors for signal-processing applications, announced today two new ultra-low-distortion differential amplifiers that set new performance standards for linearity and power consumption. The ADL5561 and ADL5562 differential amplifiers efficiently drive high-speed, high-IF sampling ADCs (analog-to-digital converters) required by today’s advanced communications systems. The ADL5561 and ADL5562 are capable of maintaining performance while driving ADCs up to 500 MHz, exceeding the industry’s previous maximum of 380 MHz, set in 2005 by ADI’s AD8352 differential amplifier.

On-chip, user-selectable gain-setting resistors enable ADI to provide detailed specifications at common IF frequencies (70 MHz, 100 MHz, 140 MHz, and 250 MHz) and common gain settings (6 dB, 12 dB, 15.5 dB). This degree of specified performance simplifies and expedites the design process, provides previously unattainable flexibility, and allows the designer to exploit fully the amplifier’s performance at multiple gain settings and IF frequencies. Additionally, the pin-compatible ADL5561 and ADL5562 allow the user to select power consumption and performance to meet the requirements for a given application.

The ADL5561 and ADL5562 amplifiers drive 12- to 16-bit ADCs at the highest practical IF frequencies for use in next-generation communications systems, such as 3G LTE (Long-Term Evolution) and NGMN (Next Generation Mobile Networks). In today’s demanding advanced-radio applications , lowering the distortion level of the ADC driver improves system performance at higher frequencies by helping to maximize the receive channel’s SFDR (spurious free dynamic range) and minimize its SNR (signal-to-noise-ratio). This improvement minimizes the number of IF frequencies within the radio design, resulting in lower power, cost, component count, and board area, and advancing system-level performance in applications such as wireless base stations, cable communications, medical and instrumentation, military and satellite communications.

ADL5561 and ADL5562 set new industry standards with exceptional performance and low power within small footprint package.

The 2-GHz ADL5561 ultra-low-distortion differential amplifier consumes just 40 mA, making it ideally suited for use in sub-140 MHz IF applications. The ADL5561 beats the industry’s best performance and provides new a benchmark for performance vs. power consumption with maximum flexibility. The ADL5561 achieves distortion levels of –86 dBc HD2, –88 dBc HD3, and –95 dBc IMD3 at 100 MHz.
The 2.6 GHz ADL5562 ultra-low-distortion differential amplifier consumes 80 mA, setting a new standard for the industry’s lowest distortion for IF applications up to 500 MHz. The ADL5562 achieves distortion levels of –95 dBc HD2, –86 dBc HD3, and –96 dBc IMD3 at 140 MHz.

Both the ADL5561 and ADL5562 operate on a 3-volt power supply and are available in a space-saving 3 mm × 3 mm LFCSP. Furthermore, unlike conventional GaAs differential amplifiers, which often require the use of a transformer to perform the single-ended to differential conversion, the ADL5561 and ADL5562 can operate in fully differential circuits or provide the single-ended to differential conversion.

Pricing and availability
The ADL5561 and ADL5562 samples are available now. Production quantities will be available in April 2009. Both devices cost $3.68 per unit in 1,000-piece quantities. For the data sheet and additional information, please visit www.analog.com/ADL5561.

    Kirt Blattenberger,


RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
