Cree, Inc. will showcase its latest packaged GaN HEMT power transistors and high power amplifier (HPA) MMIC in the 2.7-3.5 GHz range (S-Band) at the 2011 IEEE International Microwave Symposium held June 7-9 in Baltimore. These products offer the industry’s best-known combination of power and efficiency, achieving typical power-added efficiencies (PAEs) of 60%. This results in a reduction in power consumption of up to 20% over existing solut...

Analog Devices, Inc. has announced new releases of two popular RF design tools. The ADIsimRF™ design tool is the software accompaniment to ADI’s complete portfolio of RF-to-digital functional blocks, allowing engineers to model RF signal chains using devices from across ADI’s RF IC portfolio.

Analog Devices, Inc. has introduced a PLL (phase-locked loop) synthesizer for wireless communication systems that features the industry’s best combination of integration, performance, flexibility and the widest continuous frequency-range coverage for a single RF device.

Luso Electronics, a supplier and installer of microwave systems and components, has introduced a low-loss alternative to standard WR75 and WR62 for cross-site runs between switching networks and antennas.

Peregrine Semiconductor Corporation has announced availability of the RoHScompliant PE42750 75-Ohm RF Switch for broadband consumer applications including cable televisions (CATV), digital television (DTV), multi-tuner digital video recorders (DVR), set-top boxes, PCTVs and video game consoles.

Crystek's CVCO55CC-0827-0840 VCO (Voltage Controlled Oscillator) operates from 827 MHz to 840 MHz with a control voltage range of 0.2V~4.7V. This VCO features a typical phase noise of -124 dBc/Hz @ 10KHz offset and has excellent linearity. Output power is typically -6.5 dBm.

Endwave Corporation has added a pair of integrated frequency upconverters to its line of high-performance GaAs monolithic-microwave-integrated-circuit (MMIC) products. The models EWU1509YF and EWU1809YF frequency upconverters operate over intermediate-frequency (IF) ranges of DC to 4 GHz and generate frequencies of 10.0 to 15.4 GHz and 17.0 to 24.0 GHz, respectively. Based on GaAs pseudomorphic high-electron-mobility-transistor (pHEMT) technology...

MSC now offers the new Encore-based SiT820X family of MEMS-based programmable oscillators from SiTime. The SiT820X family features an unprecedented 600 femtoseconds (fs) of phase jitter in the critical range of 12 kHz to 20 MHz for SONET-applications and a continuous frequency stability of ±10 ppm from -40°C to +85°C.

Switching systems are often needed to automate and speed up the testing of multiple devices in a production environment, and when making mixed signal measurements during R&D and production. Mixed signal measurements on multiple devices increases the importance of switching systems as a means of achieving high test system throughput. Still, there are a number of potential pitfalls in choosing and configuring the switch hardware and software fo...

Peregrine Semiconductor Corporation has announced availability of the RoHS-compliant PE42551 50-Ohm RF Switch for high-performance broadband RF applications such as automated test equipment (ATE), related test and measurement applications, and cellular infrastructure.
