A decade ago, "cell phones" were all about voice communication, an extension of the home phone for those who needed to be on the go. Global roaming was minimal at best, with multiple communications standards worldwide: GSM, TDMA and CDMA, primarily, with many devices carrying backward compatibility to AMPS....

Figure 1 iPhone 4 antennas (courtesy of intomobile. Most people have heard about the iPhone 4 antenna problems. Apple released the new phone with a novel set of external antennas that immediately had reception problems. The company cleverly used the stainless steel band around the phone as the antenna...

When it comes to monolithically integrating functionality, a new benchmark has been set by M/A-COM Tech Asia with the introduction of an X-band, 8.5 to 11 GHz GaAs MMIC core chip for transmit/receive (T/R) modules. This multi-function chip, the XZ1002-BD, consists of fully integrated transmit/receive switches, a low noise...

Avago Technologies' five-chip monolithic microwave integrated circuit (MMIC) solution, shown in Figure 1 , targets the expanding 38 and 42 GHz point-to-point radio markets. This solution enables the end user to source a complete RF front-end solution from a single supplier allowing for fast time-to-market. Avago designs millimeter-wave products...

GaAs MMIC SP4T Switches These two new SMT packaged GaAs PHEMT MMIC SP4T switches are ideal for industrial sensors, test and measurement, microwave radio, military EW and space applications up to 30 GHz. The HMC641LP4E is a MMIC SP4T switch that is rated for operation from DC to 20...

Industry News Agilent Technologies Inc . announced it has acquired certain assets of Signametrics , a manufacturer of PXI, VXI, PCI and USB digital multimeters (DMM), and modular switching products. These test and measurement products are commonly used in manufacturing production and automotive test systems. The acquisition expands Agilent's...

The rapid expansion of mobile radio networks has required network operators to increase mobile radio antennas and base stations, often under strict time and cost constraints. The new R&S ZVH handheld analyzer from Rohde & Schwarz was designed especially to meet such demands. Two frequency ranges, from 100 kHz...

The Mini-Circuits ZHL-100W-GAN+ is a 20 to 500 MHz, 100 W coaxial high power GaN amplifier featuring high efficiency and high IP2/IP3. It utilizes a high power GaN output stage, which offers higher efficiency (50 percent typical) than its GaAs, LDMOS and VDMOS counterparts. The ZHL-100W-GAN+ is an unconditionally...

Small Antennas: Miniaturization Techniques & Applications provides up-to-date methods on the theory and design of small antennas, including an extensive survey of small antenna literature published over the past several years. Antennas have always been difficult to miniaturize, but recent developments in novel materials, either natural or synthetic (metamaterials),...
