New Modules Simplify Design and Advances Performance of Mobile Handsets,
Access Points and Base Station Equipment
Avago Technologies today announced two new power amplifier product families designed for next generation cellular and WiMAX applications.

Avago has added the MGA-30116/-30216/-30316 family of half watt base station power amplifiers and the ALM-42316 low voltage power amplifier for mobile handset and fixed terminals to its product offerings. Avago’s new power amplifiers support cellular (GSM, CDMA, WCDMA, CDMA2000 and TD-SCDMA) and WiMAX frequencies.

More specifically, the ALM-42316 delivers 23 dBm linear output power (2.5% EVM at 64 QAM OFDM) and a high gain of 30 dB when operated at 3.3V and 400 mA. With built-in detector, bypass switch and shutdown function, the ALM-42316 is designed for (802.16e) mobile terminals operating in the 3.3-3.8 GHz frequency band and is housed in a 5 x 5 x 1.1mm molded chip-on-board (MCOB) package.

The half watt MGA-30x16 family of power amplifiers provides very high linearity and exceptional PAE (power added efficiency) at 1 dB gain compression point. It enables a common footprint and PCB layout for base station applications ranging from 750 MHz to 3.9 GHz. The MGA-30x16 family of power amplifiers is housed in a miniature 3 x 3 x 0.85mm 16-pin quad-flat-non-lead (QFN) package which allows for the design of highly compact next-generation base station equipment, such as pico or femtocell base station receivers.

The VMMK-1218 & VMMK-1225 allows a high dynamic range, ultra-low noise, high gain and single positive DC supply.

The GaAs Cap chip scale sub-miniature leadless package is small and ultra thin, yet can be handled and placed with standard 0402 pick and place assembly and work in low voltage operation and any broadband applications up to 25 GHz.

They do not require negative voltage to turn it on which translates to low cost and ease of use for the customer.

Typical Applications include:

• Low Noise and Driver for Cellular/PCS and WCDMA base stations
• WLAN and WiMAX notebook computers
• Receivers
• VSAT and SATCOM systems
• WLL and MMDS transceivers
• Military radar
• E-pHEMT applications

New BreezeACCESS EZ wireless equipment squeezes down cost of delivering personal broadband access to remote network users

Hartlepool Borough Council rolls out major European implementation of BreezeACCESS EZ gear, providing broadband access at home to disadvantaged children

The cost to network owners of providing wireless broadband access to remote users has fallen with the launch in the UK of the new BreezeACCESS EZ product from Alvarion.

BreezeACCESS EZ consists of a central access unit and individual subscriber units for each user. The subscriber unit includes a wireless radio and integrated 17dBi flat-panel antenna attached to an external wall. Each subscriber unit can provide full-duplex throughput of up to 12Mbps, supporting demanding applications such as VoIP. The maximum distance from access unit to subscriber unit is 8 miles. The devices operate in the unlicensed 4.9GHz - 5.875GHz band.

While the radio technology has been proven in previous BreezeACCESS products, the simplicity of installation and configuration of the new EZ product represents a breakthrough in cost-saving for network owners.

The subscriber units are extremely easy to install: the antenna does not require a line of sight to the access unit - simple visual aids ensure correct antenna alignment. In addition, the system is very well integrated with the Windows networking environment, which means that initial configuration of each user is quick and easy.

The system is well suited to enterprise users, campuses and public services, which want to avoid the high cost of installing permanent cabling, and which might require periodic removal of subscriber equipment and reinstallation in another location.

Ian Stevens, of Alvarion’s UK representative BFi Optilas, said that BreezeACCESS EZ is a cost-efficient, easy-to-implement solution for WISPs (Wireless Internet Service Providers) and municipal authorities operating in licence-exempt spectrums. He said: “BreezeACCESS EZ is extremely easy to set up - it is as close to plug-and-play as you can get today with metropolitan-area wireless broadband equipment.”

A major roll-out of BreezeACCESS EZ equipment has now begun in Hartlepool, where the borough council is using it to provide broadband access to disadvantaged children as part of a government programme to extend the learning environment to the home. Six hundred units are planned to be connected by July 2008.

The use of BreezeACCESS EZ has enabled Hartlepool Borough Council to pare the cost per connection. The cost of initial installation is low. In addition, initial configuration is simple, and does not require the involvement of highly-qualified and expensive network engineers.

The same economies apply when subscriber equipment needs to be removed and redeployed elsewhere, providing the council with the flexibility to provide access equipment to the right user at the right time.

Peter Lowe, Service Director at Northgate Information Solutions - Hartlepool Borough Council’s IT partner - said, “BreezeACCESS EZ really is incredibly quick and easy to set up - a subscriber unit can be installed in less than an hour. And our staff have found the configuration process very straightforward when working in a Windows environment.”

He said that Northgate had felt confident selecting Alvarion equipment because the company is a market leader in the field, and the performance and reliability of its equipment is proven.
