Small-Sized Power Amplifier Reduces Component Cost

California Eastern Laboratories (CEL) is now shipping its new uPG2251T6M GaAs power amplifier (PA). The new PA eliminates the need for RF component matching, which reduces component count, saves bill of materials (BOM) cost, and simplifies procurement.

Key Applications

The new 2251 PA is ideal for applications such as Bluetooth modules that are designed into notebooks, mobile phones, and headsets as well as 802.15.4/ZigBee modules which have wide applicability in automatic meter reading, wireless security, cable replacement, and intelligent lighting control systems. The PA boosts range for CEL's extensive line of 802.15.4/ZigBee devices.

Small Size

At 2 x 2 mm, the new 2251 is one of the smallest power amplifiers in the industry, enabling product designs where printed circuit board (PCB) space is scarce such as smart phones, digital cameras, hand-held gaming devices, and other consumer electronics.
