Response Microwave, Inc. a global specialist in providing RF/Microwave customer solutions, is pleased to announce the availability of its new product selection guide.

There are a number of communications, radar and imaging applications spanning Ka-band through W-band (26 to 110 GHz) that require transmitter output powers in the range of a few watts to a few tens of watts. Vacuum-tube sources and amplifiers have long been available that can produce output power...

For specific applications, there is a need for materials or composite structures which can reflect and/or absorb the electromagnetic (EM) energy incident upon them in a desired or controllable fashion. Such reflective EM absorbing/reflecting materials 1-3 are useful in designing smart radar cross-section (smart RCS) surfaces and radio frequency...

In recent years the VXIbus architecture has proven to be a versatile interface standard for instruments from many diverse manufacturers to operate within the same mainframe. The VXIbus incorporates the user-friendly features of instruments designed to operate within the General Purpose Interface Bus (GPIB) (for example, using ASCII-level programming)...

A family of Ultra-low ESR products has been introduced that set a new standard for low loss microwave performance. The equivalent series resistance (ESR) is half that of previous products. The series, designated UL (Ultra-low), is currently available in both 0603 and 0505 case sizes with addition parts to...

The data rate evolution necessary to meet new mobile telecommunication standards (9.6 kb/s for GSM, 115.2 kb/s for GPRS, 384 kb/s for EDGE and 2 Mb/s for UMTS) demands the use of wider bandwidth and bandwidth-efficient linear modulation techniques. Therefore, telecommunication manufacturers require improved specifications for 3G standards. In...

Advances in MIC and MMIC technology have motivated the demand for compact, high performance filters, diplexers and multiplexers used in microwave receiver systems. Combline bandpass filters have been in great demand because of their structural compactness and excellent wide stop-band performance. They are easy to fabricate in printed circuit...

Improving VSWR is typically an iterative trial-and-error exercise when utilizing either frequency or time domain information. For example, while circuit modifications which decrease time domain reflectometry (TDR) "bumps" (discontinuities) are generally a good thing, decreasing a specific TDR bump does not necessarily improve VSWR within a frequency band of...

In order to test high power amplifiers used in today's cellular base station equipment it is sometimes necessary to perform automated switching of the high power amplifiers without shutting down the system to make the RF connection. The high power RF signal must be diverted from the main signal...
