To protect expensive high power amplifiers operating at X-Band, Renaissance has developed a new broadband coaxial isolator that operates from 9 to 9.6 GHz and can handle 50 W reflected power. Insertion loss of 0.5 dB is maintained over -40 to +85 C.The reflected power is dissipated to the mounting surface with an extended heat sink that must be maintained below 50 C for CW operations.
Richardson RFPD Inc. announces that it is accepting orders for five new discrete GaN transistors from TriQuint. The new discrete gallium nitride (GaN) on silicon carbide (SiC) high-electron-mobility transistors (HEMTs) offer a range of pulsed output power covering 10 to 285 W, with operating ranges from DC to 6 GHz.
Narda offers a wide range line of PIN diode based limiters. The wideband limiters that are part of this line cover 1 to 18 GHz in one band. They support power handling of up to 6000 W of pulsed power. The limiters were designed to meet severe environmental conditions for airborne as well as for other applications.
Laser Services stocks and delivers custom laser cut microwave absorber material. One of our preferred brands is ECCOSORB® high loss microwave absorber from Emerson & Cuming. It is designed to attenuate electromagnetic interference by converting RF energy to heat.
Model SWN-2DR- STD is a SPDT solid state reflective switch capable of operating from 8 to 18 GHz and can handle 40 W of CW power. The switch has a maximum insertion loss of 2 dB, VSWR of 2.0:1 maximum and an isolation of >40 dB. It has a maximum switching speed of 150 nSec. Switching rate is 500 KHz max. Input and output connectors are SMA (F) and solder pins for TTL and power supplies.
RFMW, Ltd. announces the availability of RF absorber material tuned to customer specific applications. These free samples are electrically tuned (optimized) to absorb unwanted RF emissions between 1 and 40 GHz based on design requirements provided by the user. These magnetic “Tuned Frequency” absorbers are intended for specular reflection loss.
Linear Technology Corp. introduces the LTC3870, a dual phase synchronous step-down slave controller that can generate currents up to 240 A when paired with a companion master controller by extending the phase count in multiphase applications. Compatible master controllers include the LTC3880 and LTC3883 digital power system management controllers.
Agilent Technologies Inc. introduced its Infiniium Z-Series oscilloscopes, which can be synchronized to measure up to 40 channels simultaneously with a maximum 63-GHz real-time oscilloscope bandwidth (on up to 10 oscilloscopes). The new oscilloscopes enable engineers to effectively test devices that incorporate the newest technologies.
RFMW Ltd. announces application and sales support for high frequency oscillators and VCXO’s to 1500 MHz. These quartz-based, differential and PECL oscillators are targeted to networking and storage applications where fast delivery (less than one week) and high performance are required.
Crane Aerospace & Electronics Microwave Solutions announces the recently re-launched microwave space qualified products (MSQP) product line. This line offers a range of standard passive products including power dividers, hybrids, couplers and mixers. These products have been previously qualified to internally generated standards derived from industry standards.
