Devices RF Power Transistors The model PTF 10149 RF power transistors exhibit a linearity of ±0.25 dB over the 920 to 960 MHz band and employ the company’s GOLDMOS technology which significantly improves RF performance. Best suited for GSM mobile phone base station transmitters, the transistors offer output power...

Integrated Circuits DC/DC Converter The company’s DC/DC converter has been integrated into the Palm VII™, the first hand-held organizer equipped with a wireless antenna that allows users to access the Internet, conduct e-commerce transactions, and send and receive instant messages. The company’s patented DC/DC converter design provides the Palm...

Antennas 10 - 40 GHz Radio Antennas The FlatFire™ point-to-point radio antennas provide superior sidelobe and gain characteristics while eliminating the conventional bulky shroud, resulting in a smaller, more rugged, attractive antenna. The antennas exceed all FCC, ETSI and BAPT requirements as well as EIA-195-C and EIA-222-F standards. Although...

Materials High Performance Laminates The RO4000® and RO3000® series laminates are designed to support the economical production of high volume circuits for specific applications in wireless communications designs. The laminates feature good electrical characteristics, including stable dielectric constant over temperature and low dielectric loss. The RT/duroid,® DUROID® and TMM®...

Sources Miniature VCXOs The CFPV-41/42/43/44 series miniature surface-mount voltage-controlled crystal oscillators (VCXO) are designed for SONET/SDH transmission systems in local telephone exchanges and local or wide area networks. The oscillators offer a high degree of frequency pulling (control of the output frequency via an applied voltage), thereby allowing degraded...

Processing Equipment Laser Stencil The LPKF StencilLaser features new concepts for control technology of XY-coordinates-tables and a laser source with a pulse rate up to 5000 Hz. Optimally adjusted to stencil production, the StencilLaser provides accuracy between 3 and 5 mm. The company also offers its QuickCheck and ScanCheck...

Subsystems 300 W Power Supply The NT301 series compact, multiple output, 300 W power supply has a 3.3 V high current main output and active input power factor correction (PFC). The active PFC circuitry provides compliance with EN61000-3-2 and accommodates a wide-input voltage range of 90 to 264 V...

Test Equipment Measurement Software for RF Power Meters The 4530 series RF power meters and the model 4500A RF peak power meter/analyzer now include software that provides highly complex statistical analysis features for added capability in measuring power of next-generation wideband modulation scheme signals such as wideband CDMA, EDGE...

Tubes Traveling-wave Tube The model TH 3875 traveling-wave tube (TWT) utilizes two technologies: the helix delay line, which ensures large instantaneous bandwidth, and a Wehnelt electrode in the electron gun, which allows modulation of the output signal. (The tubes can operate in CW or pulse mode, depending on the...

Software EDA Simulation Software The Advanced Design System (ADS) electronic design automation (EDA) Release 1.3 software provides real-time interactive tuning of multiple parameters, analysis and synthesis of transmission lines, filter synthesis, matching network synthesis, improved noise analysis and faster large-scale circuit envelope simulations. The software operates on most UNIX...
