Improved DAC Phase Noise Measurements Enable Ultra Low Phase Noise DDS Applications

by Peter Delos and Jarret Liner, Analog Devices, Inc. In radar applications, phase noise is a critical performance metric for systems requiring high clutter attenuation. Phase noise is a concern for all radio systems, but radar in particular can require phase noise performance at frequency offsets much closer to the carrier than a communication system. […]

Step-Down Silent Switcher® 2

The LT8650S is a dual 4A, 42V input synchronous step-down switching regulator. Its unique Silent Switcher 2 architecture uses four internal input capacitors as well as two internal BST and a single INTVCC capacitor to minimize the area of the hot loops. The design dramatically reduces EMI emissions. ANALOG DEVICES, INC. (6)

Active Rectifier Controller

The Power by Linear™ LT8672 is an active rectifier controller with reverse input protection to -40V. Its 3 to 42V input voltage capability is ideal for automotive applications which must regulate through cold-crank and stop-start scenarios with minimum input voltages as low as 3.0V and load dump transients up to 40V. The unit drives an […]

µModule® Step-Down Regulator

The LTM8065, a µModule (power module) step-down regulator, has up to 40V input voltage (42V abs max), which can safely operate from unregulated or fluctuating 12 to 36V input supplies in noisy environments such as industrial robotics, test and measurement, medical, factory automation and avionics systems.

VFTT – Analog Devices

John Cowles, GM of RF and Microwave Business Unit, Analog Devices MPD: Millimeter wave frequencies will be used for cellular communications for the first time in 5G. What challenges and opportunities does this present for the microwave industry? JC: The emergence of the millimeter wave 5G frequencies at 28 and 39 GHz for cellular communications is very […]

Zero-Drift Op Amplifier

The LTC2063 zero-drift op amp draws just 1.3µA typical (2µA max,) on a 1.8V supply. This micropower amp maintains uncompromised precision: maximum input offset voltage is 5µV @ 25ºC, maximum drift is 0.06µV/ºC from -40 to +125ºC. Maximum input bias current is 15pA @ 25ºC and 100pA from -40 to +125ºC. ANALOG DEVICES, INC. (10)

DC/DC Controller

The LTC7820 is a high power fixed ratio charge pump DC/DC controller that eliminates the power inductor in a non-isolated intermediate bus converter, allowing up to a 50% reduction in circuit size and up to 4000W/in3 power density. It drives external MOSFETS in voltage divider, doubler, or inverter configurations with an efficiency of up to […]

Limiting Amplifier Module

The HMC7891 is a limiting amplifier that operates over the band of 2 to 18 GHz, with a high gain of 47 dB. It provides a saturated output power of 13 dBm over the input power range of -30 to +10 dBm, for a limiting dynamic range of 40 dB. Operating temperature is -40 to […]

Transmit LO Leakage (LOL)—an Issue of Zero-IF that Isn’t Making People Laugh Out Loud

by Dave Frizelle, Analog Devices Inc. There are several major advantages to zero-IF architecture. However, there are also some challenges that need to be overcome. Transmit local oscillator leakage (referred to as transmit LOL) is one such challenge. Uncorrected, transmit LOL will produce an unwanted emission within the desired transmission, potentially breaking system specifications. This […]

Ultra-Wideband Mixer 

The LTC5553 is a double balanced mixer providing best-in-class matched bandwidth capability from 3 to 20 GHz. It can be used either as an up- or down-converter. The device integrates an LO buffer requiring only 0 dBm input drive, effectively eliminating an external high power LO amplifier circuit. ANALOG DEVICES, INC. (139)
