Receiver greatly simplifies dual-antenna system design because it integrates antenna sensing, switching and a high-performance low-noise amplifier.
This is achieved through the use of an efficient SiGe BiCMOS process that boosts linearity and power output to the levels of gallium arsenide (GaAs) alternatives, while reducing nominal quiescent current for longer battery life.
Using the silicon-based process also improves availability, yields and cost.
"The ability to achieve the high linearity and stability required of CDMA handsets with a SiGe-based power amp is a significant breakthrough", said Jose Harrison, Director, Cellular, SiGe Semiconductor.

Complete 802.11a/b/g/n WLAN RF front-end modules provide all the functionality required between the transceiver and the antenna in dual-band Wi-Fi systems.
"Handset designers can now achieve the required performance at a fraction of the cost of most solutions on the market today.
The added benefits of ultra low power consumption and high integration strengthen our position that SiGe-based PAs will displace GaAs across 2G, 2.5G and 3G cellular markets".
SiGe's SE5102 is a single-band, two-stage power amplifier based on a highly efficient SiGe BiCMOS process that improves power efficiency, linearity and integration.
The SE5103 integrates the high-performance device into a fully matched, plug 'n' play module that contains all active circuitry including input and output impedance matching elements with a 50ohm load.
The SE5102 and SE5103 feature excellent linearity, and achieve high power output of +28dBm in CDMA operation with a power added efficiency of 39%.
On-chip protection circuitry ensures reliable performance under high voltage standing wave ratio (VSWR) conditions.
SiGe Semiconductor's SE5102 and SE5103 also offer low nominal quiescent current of 65mA, which enables long battery life.
This allows handset manufacturers to support new data services while meeting consumer expectations for talk time.
The devices also offer power down mode, and feature a low standby current of less than 2uA.
The SE5102 and SE5103 are available now.
The SE5102 is supplied in a 16-pin 3 x 3mm QFN package; the SE5103 is supplied in a 10-pin LGA package that measures 4 x 4 x 1.5mm.
SiGe Semiconductor also provides evaluation kits, supplied with full hardware and software documentation.
