The hiring process at Analog Devices is technical and multifaceted. It typically involves an assessment, technical interviews, and group and HR interviews.
On average, the process takes 23 days. Engineers tend to have the quickest hiring process (on average, ten days), whereas Product Engineer roles have the slowest hiring process (on average, 19 days).
After youve submitted your resume to Analog Devices you will be sent a link to complete an assessment. The tests typically take between 60 to 90 minutes. It focuses on job-specific knowledge as well as your cognitive ability and learning agility.
If youre applying for a technical position, anticipate up to four technical interviews lasting for one hour each. Questions will be tailored to the position that youre applying for. The technical interview questions for a coding position, for instance, will be specific to mock coding scenarios and problems.
If you are applying for a non-technical role, anticipate two to three half-hour interviews. These interview dont have any coding or other technical questions. Instead, the interview focuses on previous projects and case studies. The whole interview is quick, only takes about 30 mins.

For analog beamformers, we have recently released the ADAR1000. This is an X- and Ku-band, 4:1 analog beamformer. In addition to all the required analog beamforming functions, a unique feature for HPA/LNA pulsing through the gate control has been included. Rapid turn on/off has been demonstrated through control of the gate rather than the drain. This approach eliminates the need to switch high current through the drain. We have released application notes on possible circuit techniques for gate switching and the capability in the ADAR1000 to aid in simplification of the control circuitry around the T/R modules.
We are witnessing an historic moment for radio frequency (RF) electronics in phased array applications. Rapid advancements in the wireless industry have proliferated the integration and miniaturization of RF electronics. Many applications now reap the benefits of these achievements. The integration of large sections of the signal chain into complete integrated circuits (ICs) has enabled phased array antennas in particular. New systems are proliferating with analog beamforming or digital beamforming implementations fueled by recent IC releases into the broad markets.
For large arrays there is significant value to this improvement. For example, 100 channels can offer a 20 dB dynamic range improvement if the noise components are all uncorrelated. We have developed our own multichannel RF testbeds to ensure these parameters are understood both for our customers use of our components and for our own internal design efforts.
A fundamental physical challenge is the element spacing as a function of wavelength, which reduces as the operating frequency increases. Many systems set the element spacing at half the wavelength or less to avoid grating lobes in the antenna pattern. At L- and S-band, it is practical to fit the electronics in an every-element spacing, utilizing the latest transceivers or direct sampling converters. As frequency increases to X-band (10 GHz), it is challenging, but possible, with advanced integration. At Ka-band, it is quite challenging. As frequency increases, hybrid architectures can become more practical and a 4:1 beamformer, such as the ADAR1000, can reduce the receiver/exciter count by 4 and allow additional space to be allocated for the RF electronics.
Direct conversion architectures provide the most efficient use of the data converter bandwidth. The data converters operate in the first Nyquist where performance is optimum and low-pass filtering is easier. The two data converters work together sampling I/Q signals, thus increasing the user bandwidth without the challenges of interleaving. The dominant challenge that has plagued the direct conversion architecture for years has been to maintain I/Q balance for acceptable levels of rejection, LO leakage, and dc offsets. In recent years, the advanced integration of the entire direct conversion signal chain, combined with digital calibrations, has overcome these challenges. Our transceiver product line is based on direct conversion architectures. Where the performance is a fit, these will be the most highly integrated, economical solutions available.
