Custom MMIC, a developer of performance-driven monolithic microwave integrated circuits (MMICs), announces the introduction of the CMD204C3, a DC to 20 GHz single-pole, single-throw (SPST) MMIC switch. Also available in die form (CMD204), the CMD204C3 is the latest control device added by Custom MMIC to its growing library of standard products.
Linear Technology Corp. introduces the LTM2884, a USB µModule® (micromodule) Isolator that combines USB data communications and USB power, and guards against ground-to-ground differentials and large common mode transients.
RFMW Ltd. announces design and sales support for Peregrine Semiconductors' 10MHz to 8GHz SP4T switch. The PE42441 combines low insertion loss of 1dB with high isolation of 39dB (measured at 6GHz). Internal 50 ohm terminations give this absorptive switch a P0.1dB compression point of 31dB, a significant competitive advantage for target applications in wireless infrastructure and wireless connectivity.
The SMA-connectorized, zero-degree WPD1040A is a Wilkinson-type power divider/combiner and features a low insertion loss of 0.50 dB (typical), high isolation of 18 dB (minimum) and excellent VSWR. It is suitable for LTE and land mobile radio (LMR), as well as RF bench test and mobile base station applications.
TEGAM Inc., a leading supplier of innovative RF power measurements, was recently awarded Patent No. 8,558,556, “Planar-axial thermistor for bolometry.” This patent describes a novel way to construct very small planar thermistors on a substrate with very low heat transfer. The thermistors are more thermally isolated from the environment than are commercially-produced thermistors. Both the small size and thermal isolation make them useful for measuring RF power at microwave frequencies up to 70 GHz.
Richardson RFPD Inc. announces immediate availability and full design support capabilities for a new 0.7 to 2.7 GHz, 10 W hybrid coupler from Wavelex.
Richardson RFPD Inc. announces immediate availability and full design support capabilities for a new absorptive 75 ohm RF single-pole, double-throw (SPDT) switch from Peregrine Semiconductor Corp. (Peregrine).
Peregrine Semiconductor Corp., founder of RF SOI (silicon on insulator) and pioneer of advanced RF solutions, introduces the UltraCMOS PE42721 75-Ohm RF switch for designers of digital TV (DTV) tuner modules, cable TV (CATV) signal switching and distribution systems, multi-tuner digital video recorders (DVRs) and set-top boxes. The switch is ideal for geographic markets – such as China, Japan, Korea and Latin America – where broadband-TV devices must accommodate multiple RF inputs for cable, satellite and terrestrial reception while avoiding interference between these signals.
Peregrine Semiconductor Corp., a fabless provider of high-performance radio frequency integrated circuits (RFICs), announced the highest performance, carrier-grade Wi-Fi switch on the market. With the highest isolation by a factor of 50, Peregrine’s switch also sets a new bar in linearity, which makes it ideally suited for the fast-growing market of 802.11ac Wi-Fi access points.
MACOM announced a new integrated SPDT switch and low noise amplifier (LNA), with bypass mode, for WLAN 802.11a,n,ac network applications.
