For many years, the wireless industry has been seeking a generic RF receiver that could adapt its frequency of operation and bandwidth to the desired signal, digitize the signal at high resolution and then demodulate the signal in software. The coexistence of various cellular (2G, 3G and 4G) and...

Hittite Microwave Corp. has introduced a new high speed analog-to-digital converter (ADC) product line that exhibits ultra-low power dissipation and high cost efficiency while maintaining high performance. The HMCAD1520, HMCAD1511 and HMCAD1510 are multi-mode ADCs with integrated crosspoint switches (Mux Array). HMCAD1520 offers 12-bit resolution up to 640 MSPS...

Hittite has developed five new wideband analog phase shifters that are designed to deliver superior performance and innovative features, all within a miniature surface-mount package. These phase shifters—HMC928LP5E, HMC929LP4E, HMC931LP4E, HMC932LP4E and HMC933LP4E—are appropriate for radar systems, satellite communications, EW receivers, amplifier linearization applications and beamforming modules from 2...

Commercially available RF, microwave and optical driver amplifiers provide their best performance under specific bias conditions. The quiescent current of such amplifiers affects critical performance parameters such as efficiency, inter-modulation distortion products and noise figure. Therefore, it is crucial to bias these amplifiers accurately for best performance. Some amplifier...

Frequency synthesis is the cornerstone of all RF and microwave systems. Often dictated by specifications that push technological, spatial and economic envelopes, the design and implementation of frequency sources can often run into hurdles that force performance, schedule, or cost compromises. Hittite Microwave has one of the most comprehensive...

Integration, performance and functionality are three of the most common requests made by RF and microwave designers striving for leading-edge systems with components that can help them deliver that often elusive market edge. In the world of signal generation, Hittite Microwave Corp. is meeting these challenges with the introduction...
