A Microwave Antenna Path-alignment Test Set XL Microwave Inc. Oakland, CA Microwave links require accurate path alignment to ensure proper operation. This process has traditionally required highly trained tower crews to physically align the antennas as well as ground technicians and complex and expensive test equipment to monitor the...

A Transceiver Chipset for 2.4 GHz Direct Sequence Spread Spectrum Applications RF Micro Devices Greensboro, NC The 2.4 GHz industrial, scientific and medical (ISM) band is coming of age, largely due to the coincidental emergence of three wireless local area network (LAN) standards. However, there are still relatively few...

Programmable Attenuator Subsystems Weinschel Corp. Frederick, MD Finally there is a low cost, easy-to-use programmable attenuator for use on the test bench or in subsystem applications. The new 8310 series SmartStep™ attenuator units represent a new concept in programmable attenuation that is both flexible and easy to program. The...
