EuMW 2015: GaN RF transistors enable smaller radar units
Three new GaN RF transistors in low-cost plastic packages designed to enable smaller size and greater reliability in civilian marine, airborne and infrastructure radar systems were unveiled by Qorvo at European Microwave Week in Paris. The TGF2977-SM, TGF2978-SM, and TGF2979-SM are unmatched GaN transistors designed to operate in the 8-12GHz frequency band.
Satellite news brought to you by a Ku-Band feed
A competitively-priced Ku-Band Feed designed for SNG (satellite news gathering) applications will be showcased by Luso Microwave at IBC 2015 (Sept 11-15) in Amsterdam. The WG17 Feeds operate with linear orthogonal polarisation over a transmit (Tx) frequency range of 13.75 – 14.50GHz and a receive (Rx) range of 10.70 – 12.75GHz. Minimum Tx/Rx isolation is specified as 40dB in the Tx band and 35dB in the Rx band without Tx reject ...
Achieve control & reliability for 2.45GHz RF systems
Engineered to replace magnetrons and other vacuum tube-era technologies, an RF power transistor has been introduced by Freescale Semiconductor. The MRF7S24250N delivers exceptional precision, control and reliability for manufacturers of products targeting industrial applications such as heating/drying, material welding and plasma lighting systems; as well as medical applications used for skin treatment, bloodless surgery and cancer treatment.
2 & 4W power amplifiers suit satellite comms
M/A-COM Technology Solutions has announced the MAAP-011246, a 2W power amplifier, and the MAAP-011139, a 4W power amplifier in a SMT package. These four-stage, fully matched power amplifiers are suited for Ka-Band SATCOM applications and provide linearity for either final power amplification stages or driver stages in higher power applications.
LVPECL oscillator provides a -163dBc/Hz noise floor at 40MHz
Crystek Corporation has launched the CVPD-952, a ultra-low phase noise LVPECL oscillator providing a -163dBc/Hz noise floor at 40MHz. Compact and powerful, the CVPD-952 provides extremely low phase noise for an LVPECL oscillator, which translates to a typical phase jitter of 75fs (12kHz to 20MHz). The CVPD-952 offers a frequency range from 131 to 200MHz.
Crystal units adapted for ultra-low power wireless solutions
With 32MHz and 32.768kHz crystals, Rutronik offers powerful crystals for ultra-low power wireless solutions. These two components from Seiko Epson are perfectly adapted for the new nRF52 series of Nordic Semiconductors. The new nRF52 series of Nordic Semiconductors embeds a powerful yet low power ARM Cortex-M4 processor with a 2.4GHz RF transceiver.
TCXO operates over a 10-52MHz frequency range
Manufactured over the frequency range of 10 to 52MHz, with a tolerance ranging from ±0.5ppm, the TX SMD voltage controlled TCXO has been introduced by Total Frequency Control. The device offers low aging and low power consumption, making it suitable for GPS, WiMAX/WLAN and mobile phone applications.

HARTING joins racing team to verify RFID detection speeds
HARTING has joined forces with the University of Osnabrück in Lower Saxony, Germany, in an experiment to verify the ability of the company’s RFID systems to detect objects moving at high speeds. The object of the exercise is to determine how fast a vehicle can go and still be detected with maximum reliability using RFID. This question is highly relevant in real-world practice, as demonstrated by areas of application such as warehousing...
VCO with standby mode & low phase noise
Crystek has launched the CVHD-957, an ultra-low phase noise HCMOS VCO with standby mode, featuring an extremely low close-in phase noise of -90dBc/Hz 10Hz offset and a typical noise floor of -168dBc/Hz at 100kHz offset.
