Annual 4G M2M Cellular Module Shipments to Grow

In 2010, only about 40,000 4G machine-to-machine (M2M) cellular modules will ship. All will be WiMAX-based. In contrast, ABI Research estimates that in 2015, more than 12.6 million of the devices – including LTE-compatible models – will ship worldwide. Why would M2M communication, which usually involves relatively low data-rates,...

37 to 43 GHz Power Amplifier Family

The requirements for higher and higher data rates and the saturation of existing frequencies and networks are pushing applications higher and higher in frequency. This is true for both the "traditional" frequency bands around 38 GHz, but also at frequencies higher than 40 GHz. This movement has been consolidated...

Notch Implemented Dual Behavior Resonator Filter and Diplexer at Ku-band

This article presents a dual behavior resonator (DBR)-based microstrip filter for the realization of a diplexer at Ku-band. The transmit – receive (Tx – Rx) filter topologies are designed at the required frequency and are cascaded using an optimized T-...
Figure 1 Basic components of a transceiver front end. Modern communication systems need new filters, diplexers and multiplexers to meet electrical performance, size and manufacturing cost requirements, which are difficult to achieve using classical topologies. Diplexers are widely used in communication systems for reducing mass and volume of the...
