It is updated often and offers a complete library of downloaded data sheets for a wide variety of RF and microwave components and subsystems. New items include on-line quote forms, keyword search, expanded...

As a supplier of microwave and millimeter-wave components, Hittite Microwave Corp.’s products are found in numerous designs within the microwave radio, point-to-point/multipoint, VSAT and test equipment markets. In particular, the company’s microwave and millimeter-wave mixer ICs have been used to implement image reject mixer (IRM) and single sideband (SSB)...

Size, cost and performance pressures have driven the industry to ever higher levels of RF integration. Dramatic progress has been made in the integration of the active functions but general adoption of passive integration (integrating functions such as RF filters, diplexers and baluns) has lagged behind. The industry has...

With the emphasis today on smaller and lighter cellular phones, battery size and weight is of paramount importance. Talk time, however, must not suffer. Therefore, low DC current consumption is a must. This relates specifically to the power amplifier since it is the main current drain in the handset....

Mobility is an undeniable and unstoppable trend. It is the driving force behind wireless connectivity, allowing people to be connected to information and entertainment whenever they want, wherever they go. The applications for wireless connectivity are virtually limitless — from cell phones, laptop computers and personal digital assistants (PDA)...

Due to the fast development of wireless communications, a low cost, high performance, high integration technology is needed for system-on-a-chip (SoC) implementation. CMOS technology provides a good solution for SOC integration. 1 Recent improvements of the standard CMOS process make it possible to implement RF blocks, such as low...

Monolithic logarithmic amplifiers (log amps) can handle signals with dynamic ranges up to 100 dB. They are capable of responding to RF bursts that are as short in duration as a few tens of nanoseconds. However, when demodulating logarithmic amplifiers are used to detect fast RF bursts, strange tails...

Multifunction modules are built from many simpler building blocks. Each block can be in the form of an MMIC device, a discrete component or a hybrid device. These blocks are assembled next to each other and connected by transition lines. There are several disciplines for the assembly process. The...

In the past, voice transmission was the main issue in communications. However, new requirements have evolved from voice to data and mobile communications, which demand a larger amount of information and better quality. Because of these requirements, more complex modulation and demodulation schemes and broadband channel bandwidths are necessary...
