Nearly all tests in accordance with the Bluetooth low energy test specification V4.0 [1] can be performed using the R&S®CBT alone. Some tests additionally call for signal generators to provide interference signals. This application note describes the tests performed with additional equipment and presents straightforward solutions based on the R&S®CBT go software.

POLQA® (Perceptual Objective Listening Quality Assessment) is the next-generation mobile voice quality testing standard according to recommendation ITU-T P.863 and has been especially developed for the super wideband requirements of HD Voice, 3G, VoLTE (4G), VoHSPA and VoIP.

The RFMD® GaAs pHEMT MMIC upconverters and downconverters combine high performance and low cost packaging, making them efficient solutions, ideally suited to both current and next generation point-to-point and VSAT applications. All devices are packaged in a 5 x 5 mm QFN to simplify both system-level board design and volume assembly.

RFMD offers a wide selection of broadband high-performance symmetric switches suitable for applications in the cellular, 3G, LTE, and other high-performance communications systems. Covering single-pole double-throw (SPDT), double-pole double-throw (DPDT), and single-pole triple-throw (SP3T), these products are ideal for use in high-performance and space-constrained applications.

The RFMD® RFCA3302 is a high performance InGaP HBT MMIC amplifier designed to run from a single +5 V supply without the need for an external dropping resistor. The high gain, high linearity, and low distortion (from 40 to 1008 MHz) make this part ideal for broadband cable applications.

The RFMD® RFLA1018 and RFLA1038 are multi-stage, low noise amplifiers (LNA) with variable gain, featuring high linearity and very low noise figure. These LNAs provides over 35 dB of dynamic gain range. A noise figure of 0.9 dB and an IIP3 of 3.5 dBm at maximum gain make these components ideal as infrastructure LNAs.

Shifting landscapes suggest RF/Microwave companies keep manufacturing closer to home. The outsourcing decision for RF/Microwave (RF/MW) companies, however, has a unique set of circumstances when compared to conventional digital electronics.

This white paper summarizes the technology options for supporting voice and short message service (SMS) in LTE, including circuit switched fallback (CSFB), SMS over SGs, and voice over LTE (VoLTE). It includes background information on the standardization process, and the commercial implications for the different options. The white paper also addresses test and measurement requirements resulting from the support of voice and SMS in LTE.

Improving the accuracy of your microwave test and measurement equipment becomes increasingly important when high frequency devices are used in the transmission paths of radio, cellular, satellite and digital communications. This discussion helps to solve problems with measurement errors during and after calibration of your microwave test instrument.

A new family of ultra-reliable mixers, developed by Mini-Circuits, combines low-temperature cofired ceramic (LTCC) circuitry and specially selected semiconductor dice in a hermetically sealed case at 1/10th the price of comparable products on the market. Fully automated, tightly-controlled, and highly repeatable processes ensure excellent performance at temperatures up to 125 degrees C.
