Analog Devices has introduced four new Digital Variable Gain Amplifiers (DVGA): ADL5201 and ADL5202, which are IF DVGAs; and ADL5240 and ADL5243, which are RF DVGAs. These new DVGAs will enable the design of smaller base stations with multiple carrier capabilities for next generation wireless systems such as Long...

The promise of 3G mobile broadband has been borne out by more than 630 million UMTS and HSPA subscribers, supported by a vibrant industry ecosystem. Building on these foundations, the first commercial launches of Long Term Evolution (LTE) technology are enhancing the mobile user experience still further. However, even...

In the last decade, cellular mobile devices have undergone dramatic changes. What began as a mobile phone simply used for people to talk or text with one another has now turned into a handheld device that provides multi-functionality such as a phone, web browser, text messenger, camera, gaming unit,...

If amplifiers are used in many applications, including base stations, cable TV and instrumentation. High linearity is one of the most desired features of an IF amplifier. New applications, such as amplifiers used in cable TV, also require very flat gain and low noise. Darlington amplifiers with single or...

The last decade has seen a great burst in wireless communication technologies and their commercial implementations. Until now, the third generation (3G) mobile networks (such as UMTS and cdma2000) and 3.5G mobile networks (such as UMTS/HSPA and CDMA 1xEvDO), which can deliver data rates up to several Mbps to...

Channels allocated for wireless services are increasingly being crammed together on the frequency band while the price per MHz of spectrum remains quite high at auction. This is especially at issue for 4G signals, which are commonly located at frequencies adjacent to existing WiFi and Bluetooth channels and therefore...
